When configuring like on my redhat 7.3 box:
./configure \
                --with-apache=../apache_1.3.27
		--with-gd=/usr \
		--with-png-dir=/usr \
		--with-jpeg-dir=/usr \
		--with-zlib-dir=/usr \
		--enable-zlib \
		--enable-track-vars \
		--with-snmp=/usr/local \
		--enable-ucd-snmp-hack \
		--with-curl=/usr/local/curl \
		--with-openssl=/usr/local/ssl \
		--with-mysql=/usr/local/mysql \
		--with-freetype-dir=/usr/local/freetype2

I get a failure and this is the output of debug.log:

CONFIGURE:   './configure' '--with-apache=../apache_1.3.27' '--with-gd=/usr' '--with-png-dir=/usr' '--with-jpeg-dir=/usr' '--with-zlib-dir=/usr' '--enable-zlib' '--enable-track-vars' '--with-snmp=/usr/local/net-snmp' '--enable-ucd-snmp-hack' '--with-curl=/usr/local/curl' '--with-openssl=/usr/local/ssl' '--with-mysql=/usr/local/mysql' '--with-freetype-dir=/usr/local/freetype2'

I have tried with the default snmp .. and with ucd-snmp/net-snmp. I have modified the ld.so.conf to include the libs for net-snmp. I have also configured snmp with shared libraries .. I have tried a install to /usr/local/net-snmp and had the configure point to that dir. ie ./configure --with-snmp /usr/local/net-snmp etc...
I cant figure out what its looking for. Can someone help ?

Thanks,
rod
