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}}} See also #30849 -- Ticket URL: <https://trac.macports.org/ticket/33315> MacPorts <http://www.macports.org/> Ports system for Mac OS
