Hi all.

I have just done a vanilla install of Interchange 4.8.3
on a redhat 7.2 system with a vanilla apache config
from the Redhat RPM files. (The foundation and foundation demo
packages are also installed.)

Connecting via a browser (several tried) you get the main
interchange welcome page, but clicking on the "Admin" link
returns an error back to the browser.
---------------------
Internal Server Error
The server encountered an internal error or misconfiguration
and was unable to complete your request. Please contact the server administrator, root@localhost and inform them of the time the error
occurred, and anything you might have done that may have caused the
error.


More information about this error may be available in the server error log.
---------------------

Looking into the /var/log/interchange/error.log I find:
---------------------
192.168.1.201 9mjUodSC:192.168.1.201 - [10/January/2002:18:30:03 -1000]
foundation /cgi-bin/foundation/admin/index.html Runtime error:
Can't call method "wrap" on an undefined value
at /usr/lib/interchange/lib/Vend/Interpolate.pm line 2484.
---------------------

The line in interplate.pm reads:
---------------------
$Tag = $hole->wrap($Tag);
---------------------


Can anybody suggest the cause of this error and/or it's
solution.

I have searched the interchange mailing list archives for this
particular error and have found no matches.

I have a second server running Redhat 7.1 successfully
with the same version of Interchange, and have made sure 
that all of the perl modules are identical on both machines.

Many thanks in advance,
Morrie.
