Thanks for taking a moment to consider my problem and offer advice. I followed your suggestion and used fink to install dlcompat-dev (the other two mentioned, dlcompat and dlcompat-shlibs, were also already installed by fink).
I still get the following error when I issue the ./configure command:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --mandir=/usr/share/man --with-apxs=/usr/sbin/apxs --with-curl=/sw
checking for cURL 7.9.8 or greater... configure: error: cURL version 7.9.8 or later is required to compile php with cURL support
I have also tried taking ou the option --prefix=/usr. Any other suggestions?
