Problems with phpMyAdmin ...

[Thomas T. Veldhouse]

Recently, I pulled down the current ports on my 6.0-RELEASE system and 
ran portupgrade (-Ra).  Everything works fabulously except for 
phpMyAdmin.  Other PHP (5.1.1) applications work just fine, including 
postfixadmin and others.  With phpMyAdmin (2.7.0p2 and all previous 
versions that I have attempted manually) I simply get a empty page.  If 
I run it through Squid, I get the following.

"The following error was encountered:

    * * Zero Sized Reply *

Squid did not receive any data for this request."

I have checked my Apache (2.0) error logs and find no errors at all.  
This problem is unique to phpMyAdmin and I am truly stumped.  I have 
been through all of the documentation and I have searched Google for 
hours.  I have found MANY reports of this same issue, but none have 
found the cause (some wiped everything and reinstalled with success, but 
that is not an option).

So, does anybody here with experience with this piece of software have a 
suggestion as to its cause?

Thanks in advance,
