Here's my helping hand ticket :)

I've tested this with a personal trick to keep libgfortran.3 around; everything seems to work just fine. I'm having a little trouble building R to use gfortran-mp-7; I suppose something must be changed to the compilers PG too (other than just setting the default from gcc6 to gcc7).
