Here's a log: daboross:/home/daboross/ $ sudo revdep-rebuild Password: * This is the new python coded version * Please report any bugs found using it. * The original revdep-rebuild script is installed as revdep-rebuild.sh * Please file bugs at: https://bugs.gentoo.org/ * Collecting system binaries and libraries Could not save cache: write() argument 1 must be unicode, not str * Checking dynamic linking consistency Your system is consistent daboross:/home/daboross/ $ sudo revdep-rebuild.sh * Configuring search environment for revdep-rebuild * Checking reverse dependencies * Packages containing binaries and libraries broken by a package update * will be emerged. * Collecting system binaries and libraries * Generated new 1_files.rr * Collecting complete LD_LIBRARY_PATH * Generated new 2_ldpath.rr * Checking dynamic linking consistency [ 100% ] * Dynamic linking on your system is consistent... All done. daboross:/home/daboross/ $ sudo revdep-rebuild --version revdep-rebuild 0.3.2-r1 The tool itself seems to be completely working, it just doesn't "save the cache". The message is reproducible, by that I mean it happens every time I run revdep-rebuild if I run it multiple times. If there is any other information I can provide, I will be happy to do so.
what python version is this happening? Do you have it installed to other python versions? What happens if you eselect those pythons then run it?
The error occurs when python2.7 is selected, but not with python3.4.
The message is slightly different from the one in bug 589130, comment #0, but the patch referenced in that bug is for a write() call: https://gitweb.gentoo.org/proj/gentoolkit.git/commit/?id=c8783ccb225cddb43052463c092e8edc091c371a
I'm seeing the same error message with app-portage/gentoolkit-0.3.2-r1 and Python 2.7.12 on an amd64 system.
Same thing happening here: $ emerge --info Portage 2.3.0 (python 2.7.12-final-0, default/linux/amd64/13.0/desktop/plasma, gcc-4.9.4, glibc-2.22-r4, 4.4.39-gentoo x86_64)

Please test gentoolkit-0.3.3 to see if it fixes the write() problem for you.
To install gentoolkit-0.3.3 on a stable system, you should create a setting like this in /etc/portage/package.accept_keywords: =app-portage/gentoolkit-0.3.3 ~amd64 There's some more info here: https://wiki.gentoo.org/wiki/ACCEPT_KEYWORDS
app-portage/gentoolkit-0.3.3 appears to resolve the issue on my amd64 system with Python 2.7.12 - at least the message is gone.
