sage-on-gentoo:

The subject libm4ri will not build here (amd64) with use, openmp. The  
configure option
--enable-openmp doesn't appear to take. I get

	configure: WARNING: unrecognized options: --enable-openmp

and a subsequent make gives

/bin/sh ./libtool  --tag=CC   --mode=compile gcc -std=gnu99  
-DHAVE_CONFIG_H -I. -I./src     -fopenmp  -g -O2 -MT

With use, -openmp it does build.
