OK, bear with me. I've screwed up once in a big way already today. ;-)

I have the newest version. I downloaded it a second time and installed it
again just to make sure.

Running a test script phpinfo(), one of the things I get under Configure
Command:

../configure' '--with-xml' '--with-apache=/usr/local/src/apache_1.3.12'
'--enable-versioning' '--enable-ftp' '--with-mysql=/usr/local/mysql'
'--with-pdflib=/usr/local/pdflib' '--with-zlib-dir=/usr/local/zlib'
'--with-png-dir=/usr/local/libpng' '--with-jpeg-dir=/usr/local/jpeg'
'--with-ttf=/usr/local/freetype' '--with-gd=/usr/local/gd'
'--with-tiff-dir=/usr/local/tiff' '--enable-track-vars'

If this is the config commands that Tenon used to compile PHP4, then it was
linked statically (as opposed to a shared Apache module via APXS) into the
Apache binary, and support for MySQL, PDFlib, Zlib, etc. are embedded into
the PHP4 library.

Wouldn't the config commands be the following if it were compiled shared?

../configure' '--with-xml' '--with-apxs' '--enable-versioning' '--enable-ftp'
'--with-mysql=shared' '--with-pdflib=shared'
'--with-zlib-dir=/usr/local/zlib' '--with-png-dir=/usr/local/libpng'
'--with-jpeg-dir=/usr/local/jpeg' '--with-ttf=shared'
'--with-gd=/usr/local/gd' '--with-tiff-dir=/usr/local/tiff'
'--enable-track-vars'

Well, Tenon has pretty much included everything and the kitchen sink. ;-)
I'm just desperately needing the FrontBase extension compiled in. I could
compile it myself, but I'd loose all the other modules that Tenon compiled
into PHP4. Some of which I have not been able to successfully compile
myself, such as FreeType and PDFlib.

When you make changes to open source software to get it to compile on Mac OS
X Server, do you submit those diffs to the authors?
