I tried building Husky tools with PREFIX set to /opt/husky and discovered a flaw in the build system: it adds -L${PREFIX}/lib to compilation command correctly but forgets to add this directive while linking (at least for fidoconf). Thus if ${PREFIX}/lib is not in compiler library search path linking fails complaining to library not being found.
This is minor as long as it seems that most users build to their /usr/local instead of smth different but it's better have that fixed.
Also I found no means to inject my LDFLAGS to the build system - imho it's better to have some "common" LDFLAGS var in the beginning of huskymak.cfg not to edit each and every Makefile in the project tree. I managed to compile Husky tools with "-L/opt/husky/lib -Wl,-rpath=/opt/husky/lib" by overriding OPTLFLAGS but this is not the solution, as for me.
This is quite old; will need to verify if the issue is still present and/or has already been resolved.
