[Bioperl-l] bio::graphics::panel under mod_perl

[Lincoln Stein]

Funny; this problem is not occurring for me, and I use 
Bio::Graphics::Panel under mod_perl all the time on multiple web 
sites.

It sounds like a GD problem. My usual advice on these occasions (when 
GD is acting up) is to search and destroy all old versions of libgd, 
then reinstall libgd and GD from source.  In your case, you might 
also try doing the same for libpng and libz -- particularly if you 
haven't updated in a while since there is a security hole in libpng 
2.0.26.
