I've used that for several packages that some researchers wanted. Be warned:
how easy or difficult it is to build depends *entirely* on the programming
competency, NOT the subject matter expertise, of the project contributors.
sci-kit was *very* easy to build. So was another, which I forget the name of
now. bio-perl was a disaster, and took weeks - a lot seemed to have been built
on ubuntu, and some... I have *no* idea - BSD? Solaris? - but a number of
modules had *hard-coded* into them /usr/bin/perl, and a few
/usr/local/bin/perl, and on, and on, and oh, you need this module, and that, -
it was something like 10 other modules, and *then* you find in the docs about
the two major packages that have a circular dependency!
This is just to warn you... but when the code is code, it works beautifully.
