Hello again, everybody. I'm afraid I have another problem I need some advice on. It's not exactly SuSE-specific, but since it *is* on my SuSE 9.1Pro system... I've spent somewhere between 20 and 30 man-hours, over the past couple months, Googling and trying to pick apart this problem piecemeal, but I just haven't gotten anywhere. I guess it's time to give up and ask for help. Here's the problem: I have several rpm-installed apps (meld, for example) that, despite being installed successfully, will not run. I generally get something like this: No module named pygtk Meld requires a recent version of pygtk. pygtk-1.99.15 or higher is recommended. Now, so far I've uninstalled gtk and python using YAST, upgraded to the newest versions of both, run apt-upgrade, and spent a *whole* lot of time on Google. It appears that my problem may lie in /usr/bin/env, which apparently points different apps to which version of python they're going to use, but I've come up completely empty looking for information on how to fix it. It's probably one of those "everybody knows it" things that I don't know the right terminology to craft a proper search term for, just like so many other Linux questions... I also eventually discovered that changing the parameter in the #! line in /usr/bin/meld (for example) to point at the newest python version *should* have worked, but I ended up with the same error messages as above. At this point, my best guess is that I've managed to completely hose something in the course of my stumbling around, but I don't know what. I think my best option at this point is to completely wipe out my old python and gtk installs and just install the latest versions, but as I said I've already tried this using YAST and apt (more than once), and it's had no effect. I'm obviously missing something, but I don't know what, and I haven't been able to find anything that would point me in the right direction (darned frustrating, that). So if anyone has a suggestion (preferably less drastic than "wipe hda and re-install SuSE), I'd be very grateful.
