Hi,
A good way to find which version of a package you have installed is to look in /var/log/packages
A quick grep for "pyQt" in my /var/log/packages gave:
Code:
-rw-r--r-- 1 root root 9081 2005-10-08 17:13 PyQt-3.14-i486-1asz
which tells me that I have version 3.14 installed on my -current, and that it's most likely not part of Slackware since it has the -lasz extension.
So - if you have installed Qt yourself, let's hope you installed it the recommended way through a package with installpkg, and you can check /var/log/packages for "Py*" and find it there. If not - check /usr/doc/PyQt* - it should contain the version number. If not - chances are you may not even have the complete package installed.
Hope this helps..
