The thorn ExternalLibraries/FFTW3 does not build on Hopper. The error message is

This is probably a configuration issue; this routine does exist, but the compiler may not be linking agains the libiomp5 or libirc libraries that define it.

The issue was that acml provides an outdated copy of libirc. The solution is to provide a non-outdated copy of libirc ourselves. Corrected in Simfactory.
