Hi, To help support of current gLite grid middleware and some scientific applications (like root) that rely on interpreters like Python and perl with SW specific modules provided by the SW as 32-bit shared libraries, it'd be nice to have the 32-bit version of these interpreters part of the compatibility mode (or at least of the distribution) for 64-bit distributions. Python is really critical, not sure perl is so important... Based on LAL experience, Python is not a real problem. 32-bit version of Python (from 32-bit SL distrib) is installing fine on 64-bit with the exception of Python binary which is not installed as it will overwrite 64-bit version. At LAL, we build a RPM providing only this binary with the name 'python32'. Probably it'll not be difficult to have the 32-bit RPM checks if it installed on 64-bit and installs binary with an alternative name. This would make the things easier and allow seamless installation of 'compatibility mode' Python. It would add the benefit of 'standardazing' the name of 32-bit Python binary on 64-bit platform.
