Replacing Sablotron backend with libxslt (gnome) backend for XSLT extension

After reading /ext/xslt/README.XSLT-BACKENDS in the source, specifically.... <snip> Config.m4 --------------------------------------------------------------------------- ---- The XSLT extension's "magic" really occurs in the config.m4 file. Here you must add a couple of things in order for your backend to be enabled. Its a bit too complex to describe (but easy to implement and understand). Take a look at config.m4 (which is well commented) to see what is necessary. Makefile.in --------------------------------------------------------------------------- ---- Simply add the source files for your backend to the LTLIBRARY_SOURCES variable and you're all set with this file. </snip> ...and having various compilation/linking/performance problems with the default Sablotron backend, I am seriously interested in replacing it with the libxslt (gnome) libraries. I hacked around with the Config.m4 and Makefile.in files as noted in Sterling's comments to see if I could get PHP configure/make to accept libxslt sources/libraries (after successfully compiling/installing them) in place of Sablotron....but no success. Before spending hours/days trying to do this methodically and painfully (since I have always just configured/made PHP "by the book" and am a recent ASP/IIS convert), I was hoping that somebody, somewhere has already done this and just not posted or documented it (or at least thought about it).
