Howdy Todd,

You could try:

preinstallopts = "sudo "   # be sure to have a trailing space in the quotes

though you might have to add NOPASSWD: to your line in the sudoers file
(not sure how EB would deal with the password prompt).

I am trying to build Singularity:

This requires that the “make install” step be performed as root (sudo make

What would be the advisable way to proceed? An new ConfigureMake easyblock that 
has “sudo” in the “make install” step?
