IIRC TNF currently supports two versions of NetBSD 4.x and 5.x. Right?
At home I'm running NetBSD-5.0 where lsof-220.127.116.11.1nb5 is installed,
that is lsof built for NetBSD-4.0.
It works *perfectly*.
So, original problem doesn't exist even on NetBSD.

I didn't read lsof sources and didn't compare kernel headers but I know
exactly that lsof built with 2.6.18 kernel headers works perfectly on
Linux-2.6.26. I'd like to see OS version removed from PKGNAME under
Linux by default. Patching pkgsrc sources is not a good solution
(actually they are already patched).

Package's PKGNAME just cannot contain an information about all
incompatibilities between different kernels of libcs (why not to add a
libc's version to PKGNAME too ;-) ). As OBATA Akio said PKGNAME's
purpose is different.

No. One of the system I'm running have 18.104.22.168-vs22.214.171.124ext kernel
version which is incompatible with pkgsrc dewey convension and is larger
and messier than 2.01.01alpha59pre2nb1.
That is OS version just breaks the package.

Actually it doesn't. See above. Original problem doesn't exist for
supported versions of NetBSD and doesn't exist on other systems.
