It seems i have two python2.6 folders located in /usr/lib vs /usr/lib64 respectively. Most python stuff (source) is in /usr/lib64/python2.6 but when in installed packages they have been put into /usr/lib/python2.6 How the system decides which directory to go when python is requested, and how it finds the packaged i installed? Thanks

Architecture-dependent python modules go in /usr/lib64/python*, while architecture-independent modules go in /usr/lib/python*. Python's module path checks both for modules when importing.

How the system decides which directory to go when python is requested, and how it finds the packaged i installed?

Properly packaged modules in Fedora use get_python_lib() from distutils.sysconfig. -- Todd OpenPGP -> KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If a pig loses its voice, is it disgruntled? -- George Carlin

Your 32-bit programs use the libraries in /usr/lib and 64-bit programs use the libraries in /usr/lib64. This is hard-coded into the programs when the packages are compiled. N.B. if you build 64-bit rpms using source packages from other distributions that don't use this convention, you may end up with 64-bit libraries in your 32-bit /usr/lib hierarchy. These may inadvertently overwrite existing 32-bit libraries of the same name, rendering the 32-bit programs that depend on them non-functional. -- -John (john(a)os2.dhs.org)
