APXS failure on ./configure

I am running Solaris 7, up-to-date patches, Perl5, Apache 1.3.9 with DSO support, and PHP-4.1.0. On my ./configure attempt, I get the following from apxs. Sorry, I was not able to successfully run APXS. Possible reasons: 1. Perl is not installed; 2. Apache was not compiled with DSO support (--enable-module=so); 3. 'apxs' is not in your path. Try to use --with-apxs=/path/to/apxs The output of /usr/sbin/apxs follows /usr/sbin/apxs: require: not found /usr/sbin/apxs: use: not found /usr/sbin/apxs: package: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: my: not found /usr/sbin/apxs: syntax error at line 87: `^' unexpected configure: error: Aborting Its pretty obvious APXS is being handed an incomplete configuration file, but I can't find out what it is. Has anyone seen this before? I am pretty confident of the rest of the configuration and compile tools. ./configure works cleanly. I just need the DSO support.
