Comment (by blb at macports.org):

 The current workaround in trunk doesn't seem to fix this one, so I had to
 use your unsetenv also in mportinit (at
 [http://trac.macports.org/browser/trunk/base/src/macports1.0/macports.tcl#L667
 line 667].  After that, the env was properly cleaned (it seems to happen
 earlier than the typical occurrence of the Tcl env bug).
