Well, you have at least two choices regarding PYTHONPATH; put it in
the system wide shell profile (/etc/profile), or your per-user shell
profile (.bashrc, .cshrc, both if you use both shells).  This really
has little to do with Python, use private-email if you need help with
shell stuff.

What I'm wondering is if it is Blender you need to tell about Python
modules, or Python you need to tell about Blender modules?  In the
first case, setting the PYTHONPATH in the environment is probably the
thing to do; in the second case it would be best to but the Blender
modules on the sys.path.

What I would do is find the location of the modules that are not being
found automatically, if they are not on the sys.path then make a
symlink from the dir containing the missing modules to inside a dir on
the sys.path.  Exactly where this link points to depends on the
characteristics of the modules and whether or not Blender (assuming
Blender module are out of place) is from a .rpm or not.  If the Python
code in Blender depends on Python-1.5, then use
/usr/lib/python1.5/site-packages; if it will work with any version of
Python, use /usr/lib/site-python; if you built Blender yourself, use
/usr/local/lib/{python1.5,site-packages}, as appropriate.
