Problems with rxvt-unicode after installing

["Silas Justiniano" <silasju%gmail.com@localhost>]

Hello all!

I just installed rxvt-unicode-8.1 from pkgsrc/x11/rxvt-unicode.

It runs fine, there is transparency and so, but some programs act
strangely (less, more) and some don't run. vi outputs: "rxvt-unicode:
unknown terminal type" and irssi: "Termcap not found for
TERM=rxvt-unicode". There is, though, the
/usr/pkg/share/terminfo/r/rxvt-unicode file.

pkgsrc should handle system files in a way that this application
worked fine, shouldn't it? Is the package broken or (more possible) am
I doing anything wrong?

Thank you very much!
