I have no idea what causes this error and what it means exactly, but let's try stuff, maybe we are lucky.

It looks like someone started to add OSX Makefiles to the crashmail repo, but never finished the job. The only difference between 'make linux' and 'make osx' seems to be the usage of clang instead of gcc as a compiler. I assume you created a Makefile.osx in jamlib too.

First I would try to build chrashmail with gcc, it might just work:
make cleanlinux
make linux

Alternatively change gcc to clang in the src/oslib_linux/Makefile and try
make cleanlinux
make osx
