I meant either RPATH or RUNPATH (whatever is used by ld). Here it
would be RPATH. Under Debian jessie, here's what I got for MPFR:
/home/vlefevre/debian8/gmp/k10/lib was the current installation

the directory from the build tree. You should have got something

Not the current directory, but the directory that contains the
