O.K. folks -- pls go easy on me as I'm very new to Linux...
I'm running Fedora Core 1 and need to install some utilities which are only available in source. I didn't install the development tools when I first installed Fedora, so I am using the package management tools to add/remove applications.

I start the utility and select "development tools" and then click "update"
I get the following error:
"The following package could not be found on your system. Installation cannot continue until it is installed." The identified package is libxmls-python 2.6.6 3.
If I run up2date lib2xml it indicates I have the most current rev.
If I run YUM I get the following which seems to indicate it's already installed?! Any suggestions????

[geekdaddy@localhost geekdaddy]$ yum info libxml2

Summary: Library providing XML and HTML support.
Description:
This library lets you manipulate XML files. It includes support to
read, modify, and write XML and HTML files. It has DTD support,
including parsing and validation, even with complex DTDs. The output
can be a simple SAX stream or an in-memory DOM like representation.
In this case you can use the built-in XPath and XPointer
implementation to select subnodes or ranges. A flexible Input/Output
mechanism is available, with existing HTTP and FTP modules and
combined to an URI library.
