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.
