Here it is as promised - new version. It's supporting multiple target ID-s, log format is compatible with passwordspro (easy to copy-paste).
Known problems: salts, containing colon (:), are problematic and needs to be handled manually. It's because passwordspro is using colon as separator between fields :)
Anyway - feedback is welcome ...

// Version 1.2
// written by Janek Vind "waraxe"
// Estonia, Tartu

// 1. Fetching algorithm optimized for speed
// 2. Attack goes through $_POST, so no suspicious logs
// 3. Pretesting saves time if IPB is not vulnerable
// 4. curl extension autoloading
// 5. can work with multiple ID-s
// 6. log format compatible with passwordspro

I think you need a newer version of the CURL extenstion.
You can find infos here http://curl.haxx.se/libcurl/php/
Alternative way to crack your problem is to download new php package that includes curl (every since 4.0.2) and install it.

open your php.ini file in the php directory and look in the extensions section
for a line like this
| Quote: | | extension=php_curl.dll |
probably it's commented with a leading ;
if this is the case, uncomment it and restart the webserver.
if you have no php_curl.dll entry in the extensions section of your php.ini file, add it and restart the server. |

Thanks! Works! All as to a line extension=php_curl.dll in dynamic extension
section, I have acquired from the very beginning! The problem was in an
installation correctness php, to be exact its modules! Once again thanks you!
