How can I switch compiler from clang to gcc46?

gcc46 will be /usr/local/bin/gcc46 -- it could be that /usr/local/bin
isn't on the path that Makefile searches.

Try using the fully qualified path in those settings:

setenv CC /usr/local/bin/gcc46
setenv CXX /usr/local/bin/g++46
setenv CPP /usr/local/bin/cpp46

(Sanity check that -- I don't have gcc46 installed, so cannot confirm
those are the correct paths.)

Well, yes.  What did you expect?  Typing 'cc' at the shell prompt will
almost certainly run /usr/bin/cc and that's going to be Clang on recent
versions of FreeBSD.  What you need to do is persuade your Makefile to
run a different compiler, somewhere else in the filesystem.
