Possible context of error(s):

/usr/include/tk.h:96:13: fatal error: X11/Xlib.h: No such file or directory
/usr/include/tk.h:96:13: fatal error: X11/Xlib.h: No such file or directory

I'm confused as to why libX11 is not emerged here

dev-lang/tk-8.6.11.1:0/8.6 -abi_mips_n32 -abi_mips_n64 -abi_mips_o32 -abi_s390_32 -abi_s390_64 -abi_x86_32 abi_x86_64 -abi_x86_x32 -aqua -debug -test threads -truetype -xscreensaver

    !aqua? (
        >=media-libs/fontconfig-2.10.92[${MULTILIB_USEDEP}]
        >=x11-libs/libX11-1.6.2[${MULTILIB_USEDEP}]

In my case, Python was failing to build because crypt.h was missing.  (Actually, a bunch of packages were failing to build; Python was one of them.)  I checked another host and found that sys-libs/libxcrypt provides /usr/include/crypt.h, but this wasn't installed on the host that was having issues.  After installing libxcrypt, Python built without further complaint.  I then continued with emerge -uNDv @world, and the first thing it pulled in was virtual/libcrypt.  Are there some undeclared dependencies somewhere that could be causing this problem?

This is bug 802210 but mitigated by recent changes (see the bottom of the bug) if Python is upgraded first.
