 libzzip fails to build. It tries to build with clang and fails with the
 error message:

 {{{
 :info:build /bin/sh ../libtool --silent --tag=CC   --mode=link
 /Developer/usr/bin/clang  -O2 -arch i386 -arch x86_64 -D_USE_MMAP  -fomit-
 frame-pointer -Wall -Wpointer-arith -Wsign-compare -Wmissing-declarations
 -Wdeclaration-after-statement -Werror-implicit-function-declaration
 -Wstrict-aliasing -Warray-bounds -fstrict-prototypes -Wstrict-prototypes
 --export-dynamic -L/opt/local/lib -arch i386 -arch x86_64 -o zzipwrap
 zzipwrap.o libzzipwrap.la
 :info:build clang: error: unsupported option '--export-dynamic'
 }}}

 The build commands were

 {{{
 sudo port uninstall libzzip
 sudo port clean libzzip
 sudo port install libzzip +universal
 }}}

 As a workaround, I managed to install libzzip with the following trick:

 {{{
 sudo port install libzzip +universal configure.compiler=llvm-gcc-4.2
 }}}

Comment:

 Ok, I can reproduce this, but only when using the universal variant; if
 you don't really need a universal build, clean and build without the
 universal variant and it should work.
