font dependency with security/KeePass-2.23, lang/mono-2.10.9nb3, graphics/libgdiplus-2.10nb12 ?

[Matthias Ferdinand <mf+ml.pkgsrc-users%netzwerkagentursaarland.de@localhost>]

Hello,

I tried to install security/KeePass-2.23nb1 (using lang/mono-2.10.9nb3
and graphics/libgdiplus-2.10nb12) on a Linux system.

On the linux machine, I have X windows running (xfce4) and there are
quite a few fonts installed, even the free MS truetype fonts.

As long as I do not also install some fonts from pkgsrc, starting up
KeePass fails with the following message, indicating it is looking for
some SansSerif font:

Actually it took me quite a while to realize that it might need a font
from pkgsrc instead of the linux installation. Googling showed mainly
answers that said "oh it works for me under KDE/Gnome/..., maybe you
should switch".

KeePass runs find after installing e.g. fonts/dejavu-ttf or
fonts/ms-ttf.

I don't know if there is any mechanism to indicate font dependencies,
but some hint in the MESSAGE file of either KeePass, mono or libgdiplus
might be nice.

Or am I simply missing a way how to configure pkgsrc packages to use the
system fonts?
