Cannot compile with GCC v4.9.2

I can't seem to be able to compile Node.js on CentOS 6.6 GCC v4.9.2 ``` $ ./configure Node.js configure error: No acceptable C compiler found! Please make sure you have a C compiler installed on your system and/or consider adjusting the CC environment variable if you installed it in a non-standard prefix. ``` More details: ``` $ which gcc /usr/bin/gcc $ gcc -v Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/local/gcc/libexec/gcc/x86_64-unknown-linux-gnu/4.9.2/lto-wrapper Target: x86_64-unknown-linux-gnu Configured with: ../gcc-current/configure --enable-languages=c,c++,fortran --enable-multilib --prefix=/usr/local/gcc Thread model: posix gcc version 4.9.2 (GCC) $ which python /usr/bin/python $ python --version Python 2.6.6 ``` I have tried to set CC.. ``` $ CC="/usr/local/gcc/bin/gcc" $ set | grep CC CC=/usr/local/gcc/bin/gcc ``` but it leads to the same error. Any ideas?
