I compile a few different versions of PHP on my development server.  Every once in a while I run into a problem with PHP installing correctly with apache.

The error looks something like this:

Installing PHP SAPI module: apache2handler /usr/local/apache2/build/instdso.sh SH_LIBTOOL='/usr/local/apache2/build/libtool' libphp5.la /usr/local/apache2/modules /usr/local/apache2/build/libtool --mode=install cp libphp5.la /usr/local/apache2/modules/ cp .libs/libphp5.lai /usr/local/apache2/modules/libphp5.la cp .libs/libphp5.a /usr/local/apache2/modules/libphp5.a ranlib /usr/local/apache2/modules/libphp5.a chmod 644 /usr/local/apache2/modules/libphp5.a libtool: install: warning: remember to run `libtool --finish /home/flumpy/temp/php-5.0.2/libs' Warning! dlname not found in /usr/local/apache2/modules/libphp5.la. Assuming installing a .so rather than a libtool archive. chmod 755 /usr/local/apache2/modules/libphp5.so chmod: cannot access `/usr/local/apache2/modules/libphp5.so': No such file or directory apxs:Error: Command failed with rc=65536 . make: *** [install-sapi] Error 1

I immediately start googling for a solution to this problem and get caught up in the symptoms.  The real problem is that there is a typo in the configure line.  In my most recent case, I had a '-' instead of a '--'.
