It is necessary to install all of GCC in order for dependent programs to be able to run, and linker run-path (e.g. -R/opt/gcc-5.1.0/lib) also needs to be specified when linking the program.  There was a similar problem for libgcc_s.so but this was provided via a runtime package:

    It's possible, but I'd have to think about how best to package it up (including dependencies, etc. etc.).  I don't have any objections to including gomp in gcc-5-runtime, and modulo the must-have-the-latest-version problem, it might not be so bad.  It's something to consider for bloody & r151018.
