[gmx-users] build nuance in gmx5 (avoiding "file INSTALL cannot find gmx")

[Szilárd Páll]

You can't install into the build tree, AFAIK that's not allowed!
Install into a clean target directory instead.

Also, you "mkdir source; mv * source" step is just weird. Why move the
source around? Instead you can simply create a build directory - this
can even be in the source tree just as the uiqck and dirty install
steps suggest:
