Had to reinstall NR after an O/S upgrade - FreeBSD 9.0
Followed installation steps as before (default) as far as my memory tells me.

In the recipes_c-ansi folder [i.e. after untarring], and running make, I am getting the following :
"f77 -O -c addint.f
f77: No such file or directory"

Using gmake produces the same error message
with some additional messages - viz
"broydn.c:25: error: conflicting types for 'fmin' "

Similar messages are obtained when compiling from other source directories.

Thanks!

BTW: the file addint.f does exist.
