 When I enter "xmgr" I get the following
 {{{

 I tried following the steps below, but that didn't help.  I am currently
 running mac osx 10.6.8.

 The openmotif port did get a revision increase when libpng was updated,
 see r75159. So the only explanation I can come up with is that maybe you
 upgraded things in the wrong order by using the -n or -R options.

 When you say you "tried following the steps below," does that mean you ran
 this command?
 {{{
 sudo port -n upgrade --force openmotif
 }}}
