Mac (OSX) Error: Unresolved inheritance operation

[Keith Kaiser]

Mac users,

Recently I decided to move from OpenMotif to lesstif in hopes of  
fixing the menu issues in Xastir.

The first thing I did was selfupdate MacPorts, then I upgraded all  
installed ports, after which I used MacPorts to install lesstif  
(lesstif @0.95.0_3 (active)).

After all this prep work I went back to the source files for Xastir  
(v1.9.5) and re-installed it. I used;

'./configure'

and followed it with;

'make && sudo make install && sudo chmod 4755 /usr/local/bin/xastir'

No errors were kicked up until I tried to run Xastir, that is when I  
got the following error:

'Error: Unresolved inheritance operation'

I tried Xastir again turning on all logging (xastir -v 2047 &), below  
is the bottom of the log up to this error.

Error: Unresolved inheritance operation

The cursor is not returned until I do a control C at which time I get;

[1]+  Exit 1                  xastir -v 2047

My understanding is that an "unresolved inheritance operation" is due  
to a version mismatch of some kind, some component of Xastir is  
expecting some version of something else (maybe xfig) but it can't  
find it. What I need is someone much closer to the Unix roots of Mac  
to help me figure out where to start looking for the problem.

I'm sorry this is such a long post but I wanted to give as much useful  
information as possible to the Mac community out there in hopes of  
getting Xastir up and running again.

Thanks in advance for any and all who can shed some light on this.
