Failed to install Mod_cURL under Windows/Apache

PHP v4.2.3 with Apache 1.3.24 under Win2000 Prof SP2 Downloaded the full v4.2.3 zip package/Win binary, some weeks ago. Installation went fine. Extensions are happily included. Have had several weeks of operations. Decided to install cURL to do some URL (strangely enough) link verification-checking. Started at manual: XII. CURL, Client URL Library Functions with sent me to http://curl.haxx.se and in turn http://curl.haxx.se/libcurl/php/ Downloaded curl-7.10.2-win32-nossl which (really) only contains CURL.EXE. I cannot see any instructions telling me what to do with this/where to put it!? Moved it to the same location as PHP.EXE. It runs happily from the command line (so that's something!) Moved both the .dlls around, checked the MVC file, and uncommented the PHP.INI line - and verified it with PHPINFO(). However when a PHP script (copied straight off the PHP manual) calls curl_init () it causes Apache to crash: "Apache.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created." - restarting the Apache service and re-running results in the same error - rebooting the whole system and re-running also. - the v-server's error log shows nothing and the access log only shows the PHPINFO() mentioned - there's nothing in the Windows Event log - I can't figure out where this "error log" is created Help! I've missed something... =dn
