R help - Mar 2007 - ERROR: 'latex' needed but missing on your system.

After successfully building R on Slackware Linux v11.0 I went to make
the documentation; the texi files went fine and then I hopefully issued

make dvi

after having gotten the warning to the effect of "You cannot build the
DVI or PDF manuals" during compilation.  And, as expected I got the
error

ERROR: 'latex' needed but missing on your system.

The problem is that latex is on my system and is in root's path:

/usr/src/R-2.4.1 Super-User > echo $PATH
/usr/share/texmf/bin/:/opt/kde/bin/:/uCsr/local/stata{sic}:/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin

I can issue latex from the command line as root (su'd to root, that
is) and it will run successfully.  Also, "whereis latex" turns up
empty.

I did not have this problem on PCLinuxOS 0.93a.

Thanks for any suggestions,
Joel

It's a bit strange, because by default files like latex should be 
readable by all users. Did you install latex from source?

Try this:
As root, do 'which latex' to see where it's installed. Make sure
that
the file and directories on its path are readable by your non-root user, 
and that the directory is in the non-root user's path. The file
'latex'
might also be a symlink to some other file (as is in Ubuntu), so that 
one will also need to be readable.
