Thanks for all the help and time.
Finally, I found a rpm on the following site and get ocaml installed.
http://dries.studentenweb.org/apt/packages/ocaml/info.html
I am not sure that is a legite rpm package. The make in the math directory seems no error.
I also have images directory chown apache:apache, chmod 777 images
a math subdirectory also being created by apache inside images directory.
I have ImageMagic installed but when I put the following code in the mediawiki page
<math>\sqrt{1-e^2}</math>
I got an unknown error msg and cannot interpret the code
any suggestion
thanks jc
