libiconv doesn't seem to work on x86_64

Description

The only way I could get trunk gcc to build was by downloading libiconv source and installing it under /usr/local as follows:

export LDFLAGS=-L/usr/local/lib && ~/src/gcc/configure  --enable-languages=c,c++ --prefix=/usr/local/stow/gcc-4.7 --with-gmp=/opt/local --with-mpfr=/opt/local --with-mpc=/opt/local --with-libiconv=/opt/local && make -j8

Otherwise I would get link errors when building cc1, generated by this command in the gcc make process:

We don't support users installing things in /usr/local; it interferes with things installed by MacPorts.

Please remove or move aside /usr/local, clean the affected port, try again, and show us exactly what happened.

Huh? What affected port?

I'm trying to build gcc from source using macports' libiconv.

The build is invoked this way:

~/src/gcc/configure --enable-languages=c,c++ --disable-multilib --disable-bootstrap --prefix=/usr/local/stow/gcc-4.7 --with-gmp=/opt/local --with-mpfr=/opt/local --with-mpc=/opt/local --without-libitm
gmake

And fails as follows:

The build is fixed by compiling and installing my own libiconv in /usr/local and using that one.

Replying to dave@…:

Oh. Ok. Well there's nothing wrong with the libiconv port. Based on the line...

gcc   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wc++-compat -fno-common  -DHAVE_CONFIG_H  gcov.o libcommon.a ../libcpp/libcpp.a ./../intl/libintl.a -liconv  ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a  -o gcov

...it looks like "-L/opt/local/lib" is missing. The gcc46 port uses the configure argument --with-libiconv-prefix=/opt/local; perhaps you need to add that.
