Solved -- "make install" failed to actually install a subset of files. I had to manually copy them instead.
Specifics: I started from /home/oddron/installers/python/Python-2.7/ and executed the usual commands: $ ./configure --prefix=$HOME $ make $ make install I have found that the installer failed to install the contents of "/home/oddron/installers/python/Python-2.7/build/lib.linux-i686-2.7/", which contains *.so files. This explains why "import collections" would work from the built python in /home/oddron/installers/python/Python-2.7/, but would fail in the installed python in /home/oddron/bin/ . I manually copied the contents of "/home/oddron/installers/python/Python-2.7/build/lib.linux-i686-2.7/", to /home/oddron/lib/python2.7/ and now everything seems to work.
