make error during compilation of tinyproxy 1.8.1 missing packages?

I'm trying to compile tinyproxy for two days now on Redhat and can't seem to figure out whats missing here. The make bombs at:

make[3]: Entering directory
  GEN    tinyproxy.conf.5
a2x: ERROR: xmllint --nonet --noout --valid /backup/builds/tinyproxy-1.8.1/docs/man5/tinyproxy.conf.xml returned non-zero exit status 4
make: *** [all] Error 2

It seems to be failing to load oasis-open site for docbookx dot dtd, which I can display in a browser fine.

#  xmllint --nonet --noout --valid /backup/builds/tinyproxy-1.8.1/docs/man5/tinyproxy.conf dot xml

Am I missing an rpm package of some kind?

Thanks!

The rpm package manager doesn't deal with missing dependencies. I suggest using yum instead since it will download and install dependencies as required. You can install RPM files with yum as well as with rpm.

I'm using Yum to install all my packages. However, there is not a 1.8.1 package for tinyproxy, therefore I'm having to compile it from source.

./configure
make
make install

The make is bombing as shown above. I think its due to missing xml libraries of some kind. No one sees this?

You are missing an XML DTD (Document Type Definition) file, or the URI that it is shown to be located at is either invalid or down. That would be "www.oasis-open.org/docbook/xml/4.5/docbookx.dtd" at a guess.

Thanks Rubberman for the pointers. Whats strange is that the docbookx.dtd file via url does exist and is accessible.
