It is not possible to compile Postgres contrib/uuid-ossp on the newest release of Mac OS X, 10.8
The specific compile error:
make -C uuid-ossp install

Full log available here (not mine, but I have the exact same problem):

There is a workaround (disable uuid-ossp) but obviously this does not help those of us who require UUID support.
There are a number of bugs open:
https://github.com/mxcl/homebrew/issues/13639
https://trac.macports.org/ticket/35153
and a proposed fix which does fix the problem for me:
> This is caused by the inclusion of the system uuid.h in pwd.h. Just add the line :
>
> #define _XOPEN_SOURCE
>
> at the first line of uuid-ossp.c, and it should compile fine.
I am not sure what the "correct" fix is, but adding the above definition does fix the issue.
