Heh.  Once again I'm glad I don't upgrade proprietary warez until
dragged kicking and screaming into the previous decade.  However,
"port info" specifically boasts that FileMerge is "supported", so I
have no doubt you're seeing what you're saying.

Yes.  This is very bad news behavior.  Please report to both MacPorts
and upstream.  I just port update'd from svn this morning and there
are no MacPorts patches, so it's upstream breakage.

That's annoying.  You could try setting

[ui]
merge = /usr/bin/merge

in ~/.hgrc.
