Easybuild - simple to use - not very quick though.

   scl enable devtoolset-7 'eb Jellyfish-1.1.12-foss-2018b.eb --robot'

has been running for half an hour already.  The devtoolset was a waste 
of keystrokes - it insists on using every single tool from its 
foss-2018b collection, even though near equivalents exist, some of which 
are older than what is on the system.  (ie flex 2.6.4b vs. 2.5.37-6, a 
complete copy of python 2.7 instead of the one already present, gcc 
7.3.0 instead of the existing 7.3.1).  That build is closing in on 6 Gb 
even though a "native" Centos 7 build of Jellyfish is only 26.7Mb.  When 
Easybuild finishes its jellyfish binaries will probably be the same 

Anyway,  yet another example of "portability by duplicating most of an 
OS". Very unclear to me if "foss-2018b" is any better than Centos 7 + 
devtoolset-7, but the latter isn't an Easybuild option.

Thank goodness we don't have this philosophy for cars, can you imagine?  
You leave a Corolla to have an aftermarket stereo installed and come 
back to find most of a Camry bolted to the roof!
