Comment (by pidloop):

 Hi Ken. Well, I see all the files in /usr/local/lib are at least 2 years
 old (I think these are from back when I tried brew which I abandoned after
 they were so rude when I asked them a simple question) so for fun I did


 {{{
 mv /usr/local/lib{,-macport-test}
 }}}

 and tried again

 {{{
 sudo port clean gnuplot
 sudo port install gnuplot
 }}}

 but now I get a completely different error, see attached.
