Installing PHP4 with Oracle support

Hello everyone-- I'm installing PHP4 on a Linux RedHat 6.2 box and I'm trying to do the make command in the terminal and I get this error: /usr/bin/ld: cannot open -lclntsh: no such file or directory I do know that the clntsh is an oracle file and it's not on the hard drive anywhere and I do know that there are people out there that have had the same problem. The problem with that is that there are no solutions anywhere to this problem. Anyway, any help would be greatly appreciated! Thanks, Jay Paulson
