Issue installing GCC using homebrew (scipy package dependency) I am attempting to install the scipy (Scientific Python, including matplotlib) package using homebrew, and I noticed that it fails when it needs to install a dependency (gcc version 4.9.0).

I attempted to install it on multiple OSX versions, and even a manual method, but the error always occurs at "make bootstrap" portion.

First method:


brew tap Homebrew/versions
brew install gcc49


Result:


make[4]: *** [all-multi] Error 2
make[3]: *** [all-recursive] Error 1
make[2]: *** [all-stage1-target-libsanitizer] Error 2
make[1]: *** [stage-bubble] Error 2
make: *** [bootstrap] Error 2


Second Method:


wget ftp://ftp.gnu.org/gnu/gcc/gcc-4.9.1/gcc-4.9.1.tar.bz2
gunzip gcc*.bz2
tar -xf gcc*.tar
./configure --prefix=/usr/gcc-4.9.1 --with-gmp=/usr/local/Cellar/gmp/6.0.0a --with-mpr=/usr/local/Cellar/mpfr/3.1.2-p8 --with-mpc=/usr/local/Cellar/mpc/0.26 --program-suffix=4.9.1 --enable-languages=c,c++,fortran --with-system-zlib --enable-stage1-checking --enable-plugin --enable-lto --disable-multilib


Result:
Similar output to first one at the end of output.

Anyone know how to install this correctly, or do I need to use xcode?  Will that even work with the scipy package installed through homebrew?

---------- UPDATE -----------

Tried suggestions.  That is the "brew install gcc" and "brew install scipy"

It fails at installing gcc either way, after doing those commands I get the following.
