I just rebuilt my Macports and get the following when I try to run gv 3.6.6:
gv idl.ps Warning: No type converter registered for 'String' to 'InitialResourcesPersistent' conversion.
Warning: No type converter registered for 'translations' to 'InitialResourcesPersistent' conversion. Warning: No type converter registered for 'String' to 'Translations' conversion. Warning: No type converter registered for 'TranslationTable' to 'Translations' conversion.
Warning: No type converter registered for 'TranslationTable' to 'Translations' conversion. Warning: No type converter registered for 'TranslationTable' to 'Color' conversion. Warning: No type converter registered for 'String' to 'InitialResourcesPersistent' conversion.
Warning: No type converter registered for 'TranslationTable' to 'InitialResourcesPersistent' conversion. Warning: No type converter registered for 'translations' to 'Meta' conversion.
Bus error
And it crashes there. gv worked for me previously (I probably updated my Macports a month ago and that version worked fine). Also, if I view the file directly with gs it works.
