Cannot build PPSSPP 1.0 under Mac OSX 10.7

[-Soel-]

Hello!
I'm trying to build PPSSPP 1.0 from source under Mac OSX 10.7 but I receive the following error:

Linking CXX executable PPSSPPSDL.app/Contents/MacOS/PPSSPPSDL
Undefined symbols for architecture x86_64:
"___exp10", referenced from:
_av_strtod in libavutil.a(eval.o)
"___sincos_stret", referenced from:

_ff_ps_init in libavcodec.a(aacps.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I remember that this problem already happened in the past but was fixed, I was able to build version 0.9.9.1 without problems.

EDIT: I also tried the 1.0 version compiled by the buildbot, the one linked in the download page of the official site, and even if it says that it's compatible with OSX 10.6 or later it doesn't work and crashes on startup.
