What really stumps me (and you too, I expect) about this is the two
different error messages. Above, it looks like collect2 simply doesn't
find a -lpython2.6 anywhere. Adding . to LIBPATH does make sense.

But what on earth is this? It looks like collect2 found the library, and
told it's mate ld, which can't open it. collect2 thinks it find a file,
ld hits "No such file or directory" on the same file.

Maybe it's a dead symlink? Looking for a file with the right name and
location would find it, while opening it would hit a dead end, and
probably return "No such file "
