Comment (by chsorger):
There is a subtle change in Mountain Lion which defaults to that system
header files will use Objective C syntax constructs
although we are compiling just pure C. This explains the build error in
mercurial above. Setting the compiler flag OS_OBJECT_USE_OBJC=0
reverts this change, so that setting (globally, as I guess there is only
pure C in sage)
`export CFLAGS="-DOS_OBJECT_USE_OBJC=0"`\\
`make`
will compile mercurial.
A second build error occurred in gd-2.0.35.p7 where the header file
fontconfig/fontconfig.h was not found. If you experience this, adding the
include /opt/X11/include helps to compile gd but induces a version
incompatibility between the fontconfig and freetype later when starting
sage. A workaround for me was to compile fontconfig into the sage local
tree using the correct free type libs and then continue with make.
A third error occurred during compilation of scipy, where Mountain Lion
does not specify the correct accelerators. Here the following helps.
`export CPPFLAGS="-D__ACCELERATE__"` \\
`make clean` \\
`make`
After that sage 5.3 compiled (at least on my 10.8.1).
