rpmbuild tries to determine the file type of Guidebook.txt, which seems
to fail. You should be able to reproduce this with
$ file -m /usr/lib/rpm/magic /path/to/Guidebook.txt

If not, I have no clue what's going on.


I tried to build nethack-vultures-1.11.1-3 through mock with FC4 setup.
This failed with another error. The following command failed inside
BUILD/vultures-1.11.1/slashem/doc:

tbl tmac.n Guidebook.mn | nroff -c -Tascii | col -bx > Guidebook.txt

The problem here is that col returns 1, although the output looks usable
to me. This might be related to a patch in util-linux
(util-linux-2.12p-col-EILSEQ.patch, Bug 176441) which is only applied to
FC4 and FC5.

Workaround is quite easy. With the following change inside your
nethack-vultures-1.10.1-clawguide.patch I was able to build the package:

Current:
+GUIDECMD = tbl tmac.n Guidebook.mn | nroff -c -Tascii | $(COLCMD)
New:
+GUIDECMD = tbl tmac.n Guidebook.mn | nroff -c -Tascii | $(COLCMD) | cat

Now 'cat' is the last command and it returns 0.

HTH,
