Comment (by cal@…):

 My `bin/cabal` correctly links against the lib from libgcc:
 {{{
 $ otool -L !$
 otool -L /opt/local/bin/cabal
 /opt/local/bin/cabal:
         /opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current
 version 1.2.8)
         /opt/local/lib/libiconv.2.dylib (compatibility version 8.0.0,
 current version 8.1.0)
         /opt/local/lib/libcharset.1.dylib (compatibility version 2.0.0,
 current version 2.0.0)
         /opt/local/lib/libgmp.10.dylib (compatibility version 12.0.0,
 current version 12.2.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1197.1.1)
         /opt/local/lib/libgcc/libgcc_s.1.dylib (compatibility version
 1.0.0, current version 1.0.0)
 $ port provides /opt/local/lib/libgcc/libgcc_s.1.dylib
 /opt/local/lib/libgcc/libgcc_s.1.dylib is provided by: libgcc
 $ port -v deps gcc48
 Full Name: gcc48 @4.8.2_0
 Library Dependencies: port:gmp, port:mpfr, port:libiconv, port:libmpc,
 path:lib/pkgconfig/cloog-isl.pc:cloog,
 path:lib/libgcc/libgcc_s.1.dylib:libgcc
 Runtime Dependencies: port:gcc_select, port:ld64, port:cctools
 }}}

 The dependency is there via `hs-cabal-install` -> `ghc` -> `gcc${version}`
 -> `libgcc`.
