Hmm, right. I tried to modify the installation path (using --libdir in ./configure) to /usr/lib64, but some *.pyo objects still are installed under /usr/lib. AFAIK, these objects are bitness-dependent (i.e., if they were generated by a 32-bit Python, they can only be execute by a 32-bit Python - and vice-versa), right? Right.

Sorry, I misread you question. PYO and PYC files are not dependent on 32/64 bit sizes.

Is there any way to separate these arch-dependent files in /usr/lib and /usr/lib64 depending on their bitness? There's no need for that. Only the config/ dir which is included in the Python lib dir is dependent on the Python configuration. I'm afraid I still don't understand your point. I mean, if the *.pyo file is dependent on the bitness of the Python interpreter (as you confirmed in my first question), therefore when I decide to have both 32- and 64-bit Python on my system I must have two versions of every .pyo file: one for 32- and another for 64-bit Python. What I've missed?

Sorry for the confusion.

You should probably have a look at how RedHat or openSUSE solve these problems. Some of them have patched Python to fit their needs. You may have to do that as well. I'll sure take a look at them. Thanks!
