yes, but very strange - also mentioned clearly here:
http://people.freedesktop.org/~dbn/pkg-config-guide.html
no idea why the --debug then claims about unknown keyword.

Path position of 'NSPR' is 1
Package NSPR has -L/usr/lib64 in Libs
Removing -L/usr/lib64 from libs for nspr
Adding 'nspr' to list of known packages, returning as package 'nspr'

  line>Cflags: -I${includedir}

so seems that pkg-config does on its own lookup the 'nspr' package
because its mentioned as 'Requires: nspr >= 4.8' ...
and if you then query 'pkg-config --libs nss':
-lssl3 -lsmime3 -lnss3 -lnssutil3 -lplds4 -lplc4 -lnspr4 -lpthread -ldl
this shows that both 'Libs' from nss and nspr are then combined...

but please take my comments only as 'mentioned' - I dont have enough
pkg-config experience to suggest that we do it this or that way...
I did only mention what I found so far when testing with pkg-config.
