PHP5 compilation under redhat apxs with Apache2 problem

Hi, I tried to compile php5, but even after I installed the 2.0.48 version of the apache rpm I still had problems configuring it. Configure command I used: ./configure --with-mysql --with-libxml-dir=/usr/local/lib --enable-discard-path --with-apxs2=/usr/sbin/apxs it came to the end of the script but in the apache part I get: checking for Apache 2.0 filter-module support via DSO through APXS... no checking for Apache 2.0 handler-module support via DSO through APXS... apxs:Error: Invalid query string `APU_BINDIR'. apxs:Error: Invalid query string `APR_BINDIR'. ./configure: line 1: /apu-config: No such file or directory ./configure: line 1: /apr-config: No such file or directory expr: non-numeric argument ./configure: line 5105: test: : integer expression expected ./configure: line 5107: test: : integer expression expected yes which I don´t know exactly how to interpret. Do I need the httpd-devel rpm? I had the 2.0.45 installed but for the 2.0.48 I need the apr package, which I am not sure of wanting to install. So if you could lend me a han, I would appreciate it.
