  Can I distribute NR routines with my application?  Bound "invisibly"
  into your executable .exe file? Generally yes.  As source code,
  linkable object libraries, or DLLs? Sorry, no.

Details are at: http://www.nr.com/infotop.html#distinfo


In short their licence is not free in the DFSG sense and is not
compatible with the GPL, under which parts of ROOT are licensed.  But
then the same can be said about $ROOTSYS/LICENSE....

However, learning how a method works from reading NR and coding it up
and licensing the result as you see fit is allowed as far as I know.
