Hi Niko,
You might try 'strace gnuplot' to see exactly what's failing at run 
time.  Even if libpng is installed , you might get a missing symbol 
error for png_pass_ystart if you've built against a different version 
than what's installed.  I'd guess just building gnuplot in oe without 
first building the libs it needs is the root cause.  You could check 
your gnuplot build log to make sure headers from outside oe are not 
leaking in somehow.

If libpng is left over from building your pre-oe target file system, you 
should rebuild everything using oe.

Good luck,
John
