On one of my servers the simple problem below does not want to print. When 
I click on the PRT button, it gives

HTTP/1.1 500 Internal Server Error Date: Mon, 18 Oct 2004 18:47:47 GMT 
Server: Apache/1.3.27 (Unix) (Red-Hat/Linux) mod_ssl/2.8.12 OpenSSL/0.9.6b 
DAV/1.0.3 mod_perl/1.26 Connection: close Transfer-Encoding: chunked 
Content-Type: text/html

The httpd error_log says

[Mon Oct 18 14:47:47 2004] [error] maketext doesn't know how to 
say:!_radical_equations_100.problem (what you just saw on the screen)!as 
needed at /home/httpd/lib/perl/Apache/lonlocal.pm line 186!

Is this server missing some modules or have a conflicting module? I check 
mod_ssl and mod_perl - they are the same versions on both lib servers. 
Thanks, -hk
