Trouble compiling php4b1

I'm running Red Hat 5.2 Intel - I can't compile Apache with PHP4-b1 (not from CVS but the website). I get the following error: gcc -c -I../os/unix -I../include -DLINUX=2 -I/usr/local/php-4.0b1 -I/usr/ local/php-4.0b1/libzend -I/usr/local/php-4.0b1/libzend c gcc -DLINUX=2 -I/usr/local/php-4.0b1 -I/usr/local/php-4.0b1/libzend -I/usr/ local/php-4.0b1/libzend -I/usr/local/php-4.0b1 -DUSE_HSm ./gen_uri_delims >uri_delims.h ./gen_uri_delims: error in loading shared libraries libmysqlclient.so.6: cannot open shared object file: No such file or directory make[3]: *** [uri_delims.h] Error 127 make[2]: *** [subdirs] Error 1 make[2]: Leaving directory `/usr/local/apache_1.3.6/src' make[1]: *** [build-std] Error 2 make[1]: Leaving directory `/usr/local/apache_1.3.6' make: *** [build] Error Can anyone help me?
