Some of the executables that make up CNews check that the NEWSPATH
that they were built with match the NEWSPATH in the file
/var/lib/news/bin/config.  This is a security feature.

Unfortunately in the Slackware 2.2.0 distribution the NEWSPATH that
the executable /usr/lib/newsbin/input/newsspool was built with is:

 /bin:/usr/bin:/usr/sbin:/sbin  

whereas the NEWSPATH in the config file is:

 /bin:/usr/bin:/sbin:/usr/sbin

This causes the newsspool program to output the error that you are
seeing as it sulks that the path is not correct and renounces its
setuid priviledge.

You can't just edit the path in the config file because the executable
/usr/lib/newsbin/relay/relaynews has been built with the correct path
so modifying the config file will just cause a problem here instead.

What you really need to do is rebuild CNews from scratch.

Alteratively you could do what I did - I simply patched the newsspool
executable with a hex editor to contain the correct path.  This is
dead easy as the paths are the same size and you only need to change a
few bytes.  This hack has been working fine for me for a couple of
weeks with no problems at all.

You either accidentally changed the values for the NEWSPATH variable
in /usr/lib/news/config (may be ../bin/config) or you installed the
broken version of the CNews distribution. Either get the sources to
compile CNews for your system or run "strings newsrun" to get a list
of the values compiled into the newsrun binary. The broken version does
have different settings here than the settings in the CNews config file.
These values (NEWSPATH,NEWSMASTER,NEWSBIN,NEWSLIB,NEWSSPOOL) must be
matching exactly .
