This might violate the gpl's "mere aggregate" clause.

If AMBERTools was a series of programs that communicated with the
non-free parts of amber through system calls and sockets and such (but
not through a shared memory address space), then inclusion of
AMBERTools would be OK.
If parts of AMBERTools were compiled with amber proper to create an
amber executable in which both parts of code shared the same address
space, then both AMBERTools and amber-proper are bound by the terms of
the gpl.
If AMBERTools was distributed separately, then this is a non-issue
because amber wouldn't then be distributing ambertools.
If AMBERTools was distributed under the LGPL, then this might also be
a non-issue.

Someone mentioned a possible licensing issue earlier - perhaps they
were referring to this.
