Matthieu,
Charlie pls. help here 

  ,
About a month ago I noticed this "problem" and was given a (seemingly) simple answer (not around here):
...to check for support you do:
#perl -V | grep LARGE_FILES 
#
#If nothing comes up, then you don't have it. 
#
#> If not where is a good place to 
#> look for instructions on re-compiling perl with large file support?
#
#Download the latest source version from 
http://www.cpan.org and take 
#the default answers to the numerous questions that are asked 
#during the installation. 
Sure as hell "nothing" comes up so we (SME) don't have large file support.
Sure as hell "cpan" is a djungle to me ... wouldn't even really know what to download - before I could even answer all those questions .-/
There is: 
http://www.cpan.org/src/5.0/stable.tar.gz to download however.
Charlie: Any leads ? - I'm a cgi fumbler (@ best). 
Does it make sense to try compiling when Charlie Brady himself takes the original RH rpm ?
