I have ryssian system, so "Íå íàéäåí óêàçàííûé ìîäóëü" means "specified module not found".
When i run wakaba.pl first time after starting apache, I have an error message "perl58.dll not found, reinstalling this program may help you". I put perl58.dll into apache/bin directory, but i still have this error message and still can't run this script ><.
