Error during compiling in windows! Help!

Hi, i tryed to build the sqlcipher library with Perl and openSSL. Unfortunatly when i insert the command “perl configure VC-WIN32 --prefix=C:\folderopenssl” on the Visual Studio prompt, it say “it looks like you don’t have either namke.exe or dmake.exe on your PATH, so you will not be able to execute the command from a Makefile.”.
What can i do?
Please help me…
