Thread: Installation issues using apt-get in 11.10

not sure if correct place thread:

did clean install of 11.10 on new computer. i've been trying install python packages (matplotlib, scipy, nltk...) , keep getting dependency errors. have of packages asks (e.g. "requires numpy not installed"-- although installed numpy), while others (e.g. python-tz) have no installation candidate. know how can fix this? tried apt-get build-dep doesn't help. i'm having issues package show in online package search, apt-get return "no installation candidate"-- chromium did few days , magically showed last night.

thanks!

-edit

specifically, error python-matplotlib:
