VCS - bits/exception_defines.h file not found

When trying to download we get this message in the console. Same program works on another Mac.

14:51:51 – error – In file included from …/vexv5/gcc/include/c++/4.9.3/exception:162:
…/vexv5/gcc/include/c++/4.9.3/bits/exception_ptr.h:37:10: fatal error: ‘bits/exception_defines.h’ file not found
#include

Is this a problem with the VCS install??

Regards,
Kevin

Anyone have an update on this?
