I "try" to do so as root (this is basically a one user machine) ... but I may have installed as user. Still, it should not have brought in a complete py set of libraries. I'm going with the idea that some other package, either via apt or flatpak (which I really don't trust) decided to be nice. But it was a mess to have python distros in /usr/lib, /usr/local/lib and ./local ... I am going to really try in the future to have everything in one spot! Speaking of "one spot" I also see that some functions do not create the .pyc versions. Running as a user, the compressed version can't be created in /usr/lib/. I assume the installer is supposed to do that, but it does appear that it's not 100%. -- **** Listen to my FREE CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: b...@mellowood.ca WWW: http://www.mellowood.ca -- https://mail.python.org/mailman/listinfo/python-list
