Hi,
since our python installation is located on a symlink'ed directory,
our variables "sys.exec_prefix" and "sys.executable" can have different
paths. Therefore, the respective test in build_ext.py fails (line 202)
and a wrong
library directory is obtained.
To fix this issue, I have attached a patch that uses "os.path.samefile"
instead,
to see whether two files are identical irrespective of its path.
Greetings
Sven Schrader
ps: please CC answers to me, I'm not on the list :-)
pps: I hope the attachment isn't inline...
Fixed path comparison in cases where symlinks to python executables are used.
