New description:

 Upon installing libomp I noticed that there was an error related to not
 finding 'libxgboost.dylib'. In the installed .dylib the rcpath references
 an absolute 'homebrew' directory (I don't use homebrew).


 {{{

 % otool -l
 /opt/local/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10
 /site-packages/xgboost/lib/libxgboost.dylib
 ...
 Load command 15
           cmd LC_RPATH
       cmdsize 48
          path /opt/homebrew/opt/libomp/lib (offset 12)
 ..
 }}}

 It can be fixed with:

 {{{
 % sudo install_name_tool -rpath /opt/homebrew/opt/libomp/lib
 /opt/local/lib/libomp
 /opt/local/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10
 /site-packages/xgboost/lib/libxgboost.dylib
 }}}

 Now the rpath is correct:

 {{{
 % otool -l
 /opt/local/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10
 /site-packages/xgboost/lib/libxgboost.dylib
 ...
 Load command 15
           cmd LC_RPATH
       cmdsize 40
          path /opt/local/lib/libomp (offset 12)
 ...
 }}}

 This should probably be fixed in the port as to avoid frustrations for
 anyone installing libomp.
