I assume some variation of b) will be needed eventually, in the spirit
of openness if nothing else. I don't know what the best way to go is
by any means, or what licensing restrictions are acceptable, but the
GNU Scientific Library folks seem to have a good list here:

As a NAG replacement the most logical one seems to be slatec, to the
newbie eye at least - I suppose fortran might not help if all the calls
have to be redone to conform to a non-NAG interface anyway.
slatec (fortran) http://www.netlib.org/slatec/ I think this is public
domain.
# SLATEC Common Mathematical Library, Version 4.1, July 1993
# a comprehensive software library containing over
# 1400 general purpose mathematical and statistical routines
# written in Fortran 77.
In fortran there is also:
NSWC Mathematics Subroutine Library (fortran)
The NSWC Mathematics Subroutine Library is a collection of Fortran 77
routines specializing in numerical mathematics. It was collected and
developed by the:
Computing Systems and Networks Division
Strategic and Space Systems Department
U.S. Naval Surface Warfare Center
Dahlgren Division, Dahlgren Virginia 22448-5000
Documentation for this one is apparently poor.
CERNLIB is largely fortran and GPLed, IIRC, but the site seems to
indicate they use NAG for some parts of the system so it probably
doesn't duplicate enough NAG functionality to be useful.
Anyway, just thought I'd throw those out. 'course, all you old salts
probably knew all about all those already ;-).
