<div dir="ltr">Hello Mark and all,

<div>I just discovered a fun fact regarding an easy path to
always having the right version of common packages installed
on the local machine: just install cvmfs and access the
desired build from there, which is built and maintained there
by the developers on behalf of the LHC
experiments:multiple build options (debug, optimized builds),
multiple compiler versions. For example, just to install the
latest G4 on my local cluster, I used to have to build it
several times (mutli-thread, single-thread, debug, opt, ...)
but now I just change a couple of lines in my setup.sh to a
new target on /cvmfs and presto. There are also builds there
for the Mac. Have a look at:</div>
