You're asking does openssl fail to build? No, it builds fine.

cryptlib used to build fine on OS X, but this failure started after some recent change (either the update to OS X 10.10 or the update to Xcode 6 or 6.1).

I added -DTHIRTY_TWO_BIT to CFLAGS which resulted in the error:

./crypt/brg_types.h:108:27: error: typedef redefinition with different types ('unsigned long' vs 'unsigned long long')

Instead, building cryptlib 3.4.2 for -arch i386 instead of -arch x86_64 does work; thanks. However, building for 64-bit is preferable.
