So, if I understand correctly, split the .dSYM generation into
macports.conf (no variant required) then have a variant for building
-O0 -g? That sounds fine to me.

Will gdb look in lib/debug automatically for the symbols? All the
projects I've seen that use .dSYM have them side-by-side with the
.dylibs (or .so).
