The combination of two or all of atexit.register, easy_install and
virtualenv seems to be causing this. Unless someone feels like digging into
that (I certainly don't), there are two easy solutions:
1. Silence the warning.
2. Remove the offending import and the logging. This will only remove the
line "removing: _configtest.c _configtest.o" from the build log (x20).
