I have a working php install, but when I installed it initially, sendmail wasn't installed correctly, and thus the mail() function was left out entirely. I've since fixed sendmail, but when I try to rebuild in the following way:
rm config.cache
./configure -with-options-n-stuff
make
make install
Everything seems to work, I get no error messages, but it doesn't seem to effect the actual installation at all.
Thanks for any help on this.
