Installation Failure with Proj.dll entry Problem

[Ng Seah Chew]

I am running on Windows 2k3 with Apache 1.3.31.

I have followed the instructions on installing the MapServer 4.2 ReadMe
file.
The MapServer 4.2 is a Win32 binary installer.

I extracted the files to C:/MapServer, moved the "proj" folder to C:/Proj
and copied the mapserv.exe under "bin" directory to the apache cgi-bin
directory. and set the PATH environment variable to "C:\MapServer\lib"

when run from web browser, I get an Internal Server Error Message, and if i
double click on the Exe file, i get the following message:

"The procedure entry point pj_units could not be located in the dynamic link
library PROJ.DLL"

What have i left out during the installation? Please help. Thanks.
