Hi,

would it be possible to use a perl graphics package with loncapa?
Such as GD?
Is it considered to be a security issue?

Typing
use GD;
in line 2 of a loncapa-perl script
gives
  'caller' trapped by operation mask at /usr/lib/perl5/5.8.8/Symbol.pm 
line 127.
Compilation failed in require at 
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/GD/Image.pm 
line 6.
BEGIN failed--compilation aborted at 
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/GD/Image.pm 
line 6.

We have the need to generate on the fly graphs (graph as in graph theory)
I have never worked with perl graphics.
