You will get an error like this multiple definition of `__i686.get_pc_thunk.bx >Fix: Here is one suggestion. It causes libtool to respect $CC and $CXX. But you would have to do this for the other tools used for linking. This will add a new file called patch-configure. diff -urN /usr/ports/devel/libtool/files/patch-configure libtool/files/patch-configure --- /usr/ports/devel/libtool/files/patch-configure 1970-01-01 00:00:00.000000000 +0000 +++ libtool/files/patch-configure 2011-03-01 04:29:41.000000000 +0000 @@ -0,0 +1,26 @@ +--- configure.bak 2010-09-22 14:44:17.000000000 +0000 ++++ configure 2011-03-01 04:23:35.000000000 +0000 +@@ -27526,7 +27526,9 @@ + old_archive_cmds=$lt_old_archive_cmds + + # A language specific compiler. +-CC=$lt_compiler ++if test -z "\$CC"; then \\ ++ CC=$lt_compiler ++fi + + # Is the compiler the GNU compiler? + with_gcc=$GCC +@@ -27872,7 +27874,11 @@ + old_archive_cmds=$lt_old_archive_cmds_CXX + + # A language specific compiler. +-CC=$lt_compiler_CXX ++if test -z "\$CXX"; then \\ ++ CC=$lt_compiler_CXX ++else ++ CC=\$CXX ++fi + + # Is the compiler the GNU compiler? + with_gcc=$GCC_CXX >Release-Note: >Audit-Trail: >Unformatted:
