When building ghc-6.6 from source on FreeBSD 6, I get this error:

 {{{

 }}}

 I configured with:

 {{{
 export CPPFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib
 ./configure --prefix=$HOME/local
 }}}

 My system has /usr/local/lib/libgmp.so; /usr/local/lib is, on FreeBSD,
 traditionally not in the default search path.  It must be specified
 explicitly to the linker.


 Once I compiled cabal-setup by hand, adding -L/usr/local/lib (as shown
 above), the rest of the build completed normally.

 I'm reporting this against ghc 6.6, but I noticed it on 6.4.2 as well.
