Upgrading Expat2 in FreeBSD 5.2.1

[Lonnie Santella]

In order to install latest ports of Apache1.3 and MySQL 4.20 - I received a 
system error informing me to upgrade expat2.

So I run my CVSUP get all the latest ports, then run it again with just 
upgrading the BASE.

Now I upgrade to expat2 (expat-1.95.7) which was successful according to 
pkg_info:

However, now I can't start X - when I attempt to, I get a gray screen, a 
working mouse pointer, and a small message window that reads: "could not 
start KDEInit. Check your installation." There is only an "ok" button and 
when I click it, it goes back to text mode, with another error message which 
is repeated several times:

"/libexec/ld.elf.so.1: Shared object "libexpat.so.4" not found"

I've searched through threads and groups - no luck on this one. Why does 
this happen?  I've recreated the issue 4 times on different machines with 
fresh installs of FreeBSD 5.2.1.

How do I upgrade expat2 without this problem?

Thanks very much for your advice,

Lonnie
