 Dear all,

 I just updated to Sonoma and re-install my ports. Scotch is failing to
 build with the {{{+gcc12}}} variant:
 {{{
 clang: error: invalid library name in argument '-stdlib=macports-
 libstdc++'
 }}}
 It seems that the variant is ignored when setting the CXX variable (I
 would expect {{{g++-mp-12}}} rather than {{{clang}}} to be executed):
 {{{
 :info:configure -- The C compiler identification is GNU 12.3.0
 :info:configure -- The CXX compiler identification is Clang 15.0.7
 }}}

 I wonder if this is related to https://trac.macports.org/ticket/62678

 Best, Lars.
