[l2h] pnmtopng problem

[Seth Rogers]

The problem is probably in your LD_LIBRARY_PATH.  When you have
executables that use shared objects (.so), the OS searches the directories
in your environemnt variable LD_LIBRARY_PATH for the the necessary
libraries.  Try adding /home/ell201/netpbm/lib to it.  Good luck.
