Thanks. However, I can't reproduce this with exactly the same version of gcc(clang):

$ gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin14.4.0
Thread model: posix

on a MacBook Pro running OS X Yosemite 10.10.4. Your build log contained the
lines 

>>> ***Error: GMP self-check has failed. See
>>> bin/x86_64-apple-darwin14.1.0-gcc-default64/extern/gmp-5.0.5/build_log
>> for details.***

- have you checked what's in this file? Is the problem reproducible?

Homebrew installation itself does not contain gcc. You need to call now

	brew install gcc 

to install it. Oh, and then call

make clean
export CC=/usr/local/bin/gcc-4.9
./configure
make

since of course there is no need to use --with-gmp=no as we expect that this time GMP will be compiled.
