php_imap4r2.dll not loaded ?!?! (win2k)

Hello, I'm trying to use some POP3 functions and the manual states I would need to use the IMAP functions. So I uncommented the ";extension=php_imap4r2.dll" line in my "c:\winnt\php.ini" file. But it gave me the following error: "Unable to load dynamic library './php_imap4r2.dll' - The specified module could not be found". I read I needed the download install the "imap-4.5.tar" module. The README file has only instructions how to "make" it for UNIX. The default "MakeFile" is for UNIX. So I tried to clown around and rename "MakeFile.nt" to "MakeFile" and make it. But I only get errors: Could Not Find D:\temp\imap-4.5\c-client\LINKAGE.* NMAKE : fatal error U1077: 'C:\WINNT\system32\cmd.exe' : return code '0x1' Stop. NMAKE : fatal error U1077: 'C:\WINNT\system32\cmd.exe' : return code '0x2' Stop. I also tried this with the "MakeFile.ntk" (don't know what ntk stands for), but no fix. Can anybody help me with this problem? Regards; Eelco.
