Opinion needed - included component w/o licensing doc

["Greg Wiley" <greg@orthogony.com>]

Good day-

I am not a member of this list so please respond
to me directly.  I am a fledgling package main-
tainer and understand that legal questions should
be brought to this list.

I have taken on a small package for my first
project and have run into a licensing problem:

The package, metrics, contains a collection
of small programs.  One program was released
by it's author under the GPL, one group of
programs was released into the public domain.
Two programs, lc and ccount, however, have
no supporting license or copyright documentation.
In the case of ccount, the original author's
email address (10 years old) is available and
I will attempt to contact--but do not expect
much success.

Without evidence of any license for these
programs, I think I must assume that any use is
contrary to the authors' interests and that
including these programs in the package makes
it non-free.

Please advise.

Regards,
