Building with Sablotron

I am trying to build PHP4.1.12 with Sablotron support "--enable-xslt --with-xslt-sablot", using Sablotron-0.9 and with js-1.5rc4 installed, but when I launch Apache I get the following error: "Cannot load /etc/httpd/modules/libphp4.so into server: /usr//lib/libsablot.so.0: undefined symbol: JS_PropertyStub" I have noticed similar queries on the web, but have not found an answer yet. Any ideas on this? > NT Cheung > Executive Manager (Health Informatics) > Hospital Authority > ps why does it report /usr//lib/libsablot.so.0 with two slashes between usr and lib? pps I earlier posted a question about the build process ignoring my --with-xslt, etc options completely. I discovered that configure was barfing on another option earlier, and once configure finds a problem with a module it ignores all subsequent modules, but keeps on building to completion. I would call this, if not a bug, then at least user unfriendly.
