All the packages needed to install gnuplot through MacPorts on Lion succeed, except for aquaterm.
Installing gnuplot through Fink is far less lucky on Lion. Fink bails out after only a third of the packages needed for gnuplot have been installed, but Fink does install aquaterm.
Is there a way to 'port install gnuplot' while pointing MacPorts to the aquaterm installation generated by Fink?
Also nice would be to know of a method to install gnuplot on Lion that uses neither Fink nor MacPorts. Learning about a replacement for gnuplot itself on OSX would be handy.
