file geodatabase api on osx mavericks via brewed gdal

I've got a new machine with a fresh install of OSX 10.9, and am having trouble getting esri's file geodatabase api to work correctly with my brewed gdal.

This is a known issue, noted here: http://forums.arcgis.com/threads/95958-OS-X-Mavericks

I've tried John Tull's noted workaround:

# install gcc
brew install --enable-cxx gcc49

# noted fgdb/gdal dependency:
brew install libdap --cc="gcc-4.9"

# gdal 
brew install gdal --enable-unsupported --with-postgresql -v --cc="gcc-4.9"


# this points the fgdb libraries at gcc4.9 somehow
install_name_tool -change /usr/lib/libstdc++.6.dylib /usr/local/Cellar/gcc49/4.9-20131103/lib/gcc/x86_64-apple-darwin13.0.0/4.9.0/libstdc++.dylib /usr/local/opt/FileGDB_API/lib/libFileGDBAPI.dylib
install_name_tool -change /usr/lib/libstdc++.6.dylib /usr/local/Cellar/gcc49/4.9-20131103/lib/gcc/x86_64-apple-darwin13.0.0/4.9.0/libstdc++.dylib /usr/local/opt/FileGDB_API/lib/libfgdbunixrtl.dylib

This helps - ogr2info --formats now shows FileGDB as a valid format. However, running ogr2info on a valid filegdb gives this error:

ogrinfo(45386,0x7fff74779310) malloc: *** error for object 0x10b49dde0: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

Any idea what I'm doing wrong? I tried removing all of the gdal dependencies and letting homebrew reinstall them when calling brew install gdal with the --c"gcc-49" flag but that didn't change anything.

edit - I now see that this issue already has a thread here Homebrew OGR with FGDB support on OSX 10.9
