Mac OS 10.9 fatal error: 'tr1/unordered_map' file not found

I installed command line tools using

xcode-select --install.

If I do

cd /Library/Developer/CommandLineTools/usr/bin, I can see gcc listed there.

I am trying to install an external application on command line which give these errors

/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/ext/hash_set:205: 5: warning:
