upgrading proftpd

[maxott]

hi, people.
as i noticed that proftpd uses too much CPU, decided to upgrade proftpd version...

but i need some advice... because i may not make it correctly...

so i use
ispcp 1.0.6
ProFTPD Version 1.3.1

now i've downloaded the latest one, but dont know how to configure it to work with ispcp correctly..

i mean ./configure parameters... cant find them...

and i'm afraid i may do it wrong

thanks
