This is no surprise.  hylafax-4.0pl2 and RedHat 6.2 will not work together
by default.

Actually, it's not assumed to be old, 4.0pl2 *requires* libtiff-3.4.x, just
as it was saying.

You're new here, aren't you?  This is very sweet of you indeed, but you
just made it worse.  You'll notice that when you get to using hylafax after
compiling with this "fix" that you'll receive 8-byte fax tiff files, that
the hylafax daemons will consume nearly 100% of the CPU, and that faxing
out is impossible... among any number of other symptoms, all depending on
how you try to diagnose the problem.

I won't go into explaining the whys (you really should read the FAQ and
search through the mailing list archives before making these types of
assumptions... it'll save you time), but to use hylafax with libtiff 3.5.x
you *must* patch the source with the appropriate (available on the website)
patches (which include much more than just renaming the required version).
However, the most current hylafax version is somewhere between a fully
patched 4.1beta2 and the current CVS, so I would suggest that you use this
dandy RPM that you can get here:  (and do what you can to remove your
4.0pl2 installation)

fax-4.1beta2-5rh6.i386.rpm
