Running the command below gives the following error. It works when I run equery with Python 3. % equery u uwsgi [ Legend : U - final flag setting for installation] [ : I - package is installed with flag ] [ Colors : set, unset ] * Found these USE flags for www-servers/uwsgi-2.0: U I - - apache2 : Add Apache2 support + - caps : Use Linux capabilities library to control privilege - - cgi : Add CGI script support - - debug : Enable extra debug codepaths, like asserts and extra output.

I guess the problem is the "’" in the description of uwsgi_plugins_carbon: Python 3.3.3 (default, Jan 19 2014, 01:10:27) [GCC 4.7.3] on linux Type "help", "copyright", "credits" or "license" for more information. >>> ord("’") 8217 So maybe this is a bug in uwsgi, too?
I get the same when running "equery uses sys-devel/gcc" and I tried on different systems (with different CPU architectures) as I thought it may be a problem with one of the installs. # equery uses sys-devel/gcc Traceback (most recent call last): File "/usr/lib/python-exec/python3.3/equery", line 38, in <module> equery.main(sys.argv) File "/usr/lib/python3.3/site-packages/gentoolkit/equery/__init__.py", line 357, in main loaded_module.main(module_args) File "/usr/lib/python3.3/site-packages/gentoolkit/equery/uses.py", line 289, in main global_usedesc = get_global_useflags() File "/usr/lib/python3.3/site-packages/gentoolkit/equery/uses.py", line 158, in get_global_useflags for line in open_file: File "/usr/lib/python3.3/encodings/ascii.py", line 26, in decode return codecs.ascii_decode(input, self.errors)[0] UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 540: ordinal not in range(128)
I haven't updated yet, but for quite some time already: for me this error in the previous comment happens everytime I execute "equery u" no matter the package I always get: $ equery u dev-libs/botan Traceback (most recent call last): File "/usr/lib/python-exec/python3.3/equery", line 38, in <module> equery.main(sys.argv) File "/usr/lib64/python3.3/site-packages/gentoolkit/equery/__init__.py", line 357, in main loaded_module.main(module_args) File "/usr/lib64/python3.3/site-packages/gentoolkit/equery/uses.py", line 289, in main global_usedesc = get_global_useflags() File "/usr/lib64/python3.3/site-packages/gentoolkit/equery/uses.py", line 158, in get_global_useflags for line in open_file: File "/usr/lib64/python3.3/encodings/ascii.py", line 26, in decode return codecs.ascii_decode(input, self.errors)[0] UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 540: ordinal not in range(128)
needless to say, the problem is immediately solved by: $ sudo eselect python set 1 $ sudo eselect python list Available Python interpreters: [1] python2.7 * [2] python3.3
doesn't solve the original problem though, the package uwsgi crashes "equery u" on python-2.7.5-r3 and any package crashes this command on python-3.3.3
The underlying issue is Python changed how it detects and handles locales in Python 3 and not all of the "bugs" have been found yet in the gentoolkit code. There are two workarounds to this problem: 1. Switch to Python 2.7 when using gentoolkit 2. Set LC_CTYPE to a UTF8 locale on your system. Here is output on my dev system using python 3.3 # locale LANG= LC_CTYPE="POSIX" LC_NUMERIC="POSIX" LC_TIME="POSIX" LC_COLLATE="POSIX" LC_MONETARY="POSIX" LC_MESSAGES="POSIX" LC_PAPER="POSIX" LC_NAME="POSIX" LC_ADDRESS="POSIX" LC_TELEPHONE="POSIX" LC_MEASUREMENT="POSIX" LC_IDENTIFICATION="POSIX" LC_ALL= # equery uses gcc Traceback (most recent call last): File "/usr/lib/python-exec/python3.3/equery", line 38, in <module> equery.main(sys.argv) File "/usr/lib64/python3.3/site-packages/gentoolkit/equery/__init__.py", line 357, in main loaded_module.main(module_args) File "/usr/lib64/python3.3/site-packages/gentoolkit/equery/uses.py", line 297, in main global_usedesc = get_global_useflags() File "/usr/lib64/python3.3/site-packages/gentoolkit/equery/uses.py", line 159, in get_global_useflags for line in open_file: File "/usr/lib64/python3.3/encodings/ascii.py", line 26, in decode return codecs.ascii_decode(input, self.errors)[0] UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 540: ordinal not in range(128) # env LC_CTYPE="en_US.utf8" equery uses gcc [ Legend : U - final flag setting for installation] [ : I - package is installed with flag ] [ Colors : set, unset ] * Found these USE flags for sys-devel/gcc-4.7.3-r1: U I - - awt : Useful only when building GCJ, this enables Abstract Window Toolkit (AWT) peer support on top of GTK+ + + cxx : Build support for C++ (bindings, extra libraries, code generation, ...) - - doc : Add extra documentation (API, Javadoc, etc).

I missed "equery uses uwsgi" being broken on python 2.7 as well. The workaround for that situation is to use Python 3.3 and set LC_CTYPE to a UTF8 locale.
I've fixed the file in the tree that was causing the issue, so you should not see the problem anymore.

This is now partially fixed with the fix for bug 587606. Python 2.7 should always work now even if there are Unicode characters in the files containing USE descriptions. Python 3 still requires that at a minimum LC_CTYPE be set to a UTF-8 locale to avoid getting a traceback.
