gnuplot fails to install on OS X 10.5.8

Running "sudo port selfupdate" followed by "sudo port upgrade outdated" did not fix the problem.

Something on your system still thinks it should be using libpng 1.2, when it has in fact been updated to version 1.4 some time ago.

Does "port outdated" still show anything outdated? If so, upgrade it.

If not, you'll need to manually locate what is still looking for libpng 1.2, possibly with a brute-force search through /opt/local/lib and/or /opt/local/bin.
