PostgreSQL version: 9.1.4
Operating system: OS X 10.8 (Mountain Lion)
Description:

I'm compiling PostgreSQL 9.1.4 on OS X 10.8, and the uuid-ossp extension
doesn't compile properly, as follows:


:info:build /usr/bin/clang -pipe -O2 -arch x86_64 -Wall -Wmissing-prototypes
-Wp
ointer-arith -Wdeclaration-after-statement -Wendif-labels -Wformat-security
-fno

:info:build int uuid_compare(const uuid_t uu1, const uuid_t uu2);
:info:build ^
:info:build 3 errors generated.
:info:build gnumake: *** [uuid-ossp.o] Error 1

I'm compiling using MacPorts (http://www.macports.org/), and I've also
reported this to them.

Yeah, we've heard that already. It appears that OSSP needs to fix their
code for Mountain Lion --- Apple seem to have changed <unistd.h> in a
way OSSP wasn't expecting.
