Installing gnuplot (or similar) on Lion

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.
