Where can get depot (or just precompilled package) with Python 3.* or at least 2.6.* for ia64-hp-hpux11* ?
Packages for hppa64-hp-hpux11* (PA-RISC) can be found at ActiveState but not for Itanium.
I can't compile it by myself because of different HP-UX and ANSI-C related problems.
I am afraid the best packaged (depot) version you can currently find is 2.5.2.
There are two good sources for such packages:
You should try out the PA-RISC version. It should work but not as fast as a native Itanium binary. Aries will take care of it.
