Comment(by cjdeloye@…):

 Replying to [ticket:18181 macosx12345@…]:

 I experienced the same problem on OS X 10.4.11 (both PPC and i386) trying
 to use xmgrace (port: grace) AFTER upgrading to macports v. 1.70 and doing
 a "port upgrade outdated".

 The problem seems to come in from two name conflicts
 (_vendorShellWidgetClass, _vendorShellClassRec ) between libXm and the
 /opt/local/lib/libXt. My setup default is to use /usr/X11R6 not the
 /opt/local Xorg version of X11, so the linking against the Xorg libraries
 was unexpected.   The linking error I get when doing a 'port -v build
 openmotif' is

 {{{
 /usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: warning multiple
 definitions of symbol _vendorShellWidgetClass
 /opt/local/lib/libXm.dylib(VendorS.o) definition of
 _vendorShellWidgetClass
 /opt/local/lib/libXt.dylib(Vendor.o) definition of _vendorShellWidgetClass
 /usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: warning multiple
 definitions of symbol _vendorShellClassRec
 /opt/local/lib/libXm.dylib(VendorS.o) definition of _vendorShellClassRec
 /opt/local/lib/libXt.dylib(Vendor.o) definition of _vendorShellClassRec
 }}}


 After experimenting, I could get openmotif to compile and successfully ran
 its demo binaries in /opt/local/share/Xm when forcing linking openmotif
 against the OS X system version of X11. The problem I was running into was
 that the default linker flag order appears to be '-L/opt/local/lib
 -L/usr/X11R6/lib', which drags in the macports Xorg libraries instead of
 the system X11 libs.

 Thus, a temporary solution to this problem (albeit temporary and inelegant
 and which may not work on OS X 10.5 since the system X11 implementation is
 different) is to modify the openmotif Portfile to ensure that the
 /usr/X11R6/ branch is looked at before /opt/local by the compiler and
 linker.  Applying the following patch to the Portfile (which also removes
 the Xorg dependencies from the openmotif port) accomplishes this and
 produced a working openmotif package for me.

 To get xmgrace to work, similar changes to the configure.ldflags and
 configure.cppflags in the grace Portfile were made.
