 The latest revision of grace, 5.1.22_7, fails to build on OS X 10.8.1 with
 Xcode 4.4.1 and latest command line tools.

 The change which prompted this upgrade was apparently a libpng bump:
 {{{
 Revision 97300, 2.2 KB (checked in by rmstonecipher at macports.org, 14 hours
 ago)
 graphics/libpng upgraded to version 1.5.12, 232 dependent ports revision
 bumped due to library version number change
 }}}

 {{{
 Apple clang version 4.0 (tags/Apple/clang-421.0.60) (based on LLVM 3.1svn)
 Target: x86_64-apple-darwin12.1.0
 Thread model: posix
 }}}

 grace is listed as "nomaintainer" so I cc'd the person who checked in this
 portfile revision.   ryandesign is the libpng maintainer so he may be
 interested in this too.
