Newly installed library not detected

Hi, folks,

In preparation for installing the latest version of PAN newsreader on my
Mandrake 8.2, I needed to update libxml. So I downloaded the Mandrake
rpm and installed it with KPackage. Installation seemed to go correctly
I can now see that libxml.so.1.8.17 is in /usr/lib, and the link
libxml.so.1 points to it. But when I try ./configure for PAN, the
configuration script doesn't think it's there. Any ideas on how to get
the system to see it?

Thanks for any help, Don.
