Re: [igraph] Error importing igraph in OSX 10.10.5

[Pablo Moriano]

Hi Tamas,

I remember that just before I tried to install igraph, I typed `export 
CC=/usr/bin/gcc’ and `export CXX=/usr/bin/g++’ to declare the Apple compilers 
as my default option. Is that related with this issue? Is there any way to 
check if I have installed the C compilers (from gnu) and where? Thank you.
