Yep, I'm aware of this.

I am using the following _ugly_ workaround:

1) while running 'configure' I specify

LDFLAGS="$LDFLAGS -lmetis -l:liblapack.a"

- make sure you have 'liblapack.a' - it may be under another name.
This makes 'configure' happy WRT reported by you problem.

2) just before running 'make' my build tool edits every Makefile
containing "-l:liblapack.a" - just deletes it.

As simple/ugly as that.

  Sergei.
