adding functions to php4...

I am trying to add some statistical functions by using ext_skel script. I have compiled external C-sources and installed on my solaris2.7 box under /usr/local/lib/libstat.a . I tried ./ext_skel --extname=stat and it stopped in the middle of generating necessary files. So, I checked the ext_skel shell script and added the "" mark around $no-help( If [ ! -z "$no-help"] ... ). It worked out alright on my system. But on the next step(buildconf), I got the following messages which I had seen during "phpize". ---------------------- ..rebuilding configure /usr/local/bin/m4: autoconf.m4: No such file or directory autoconf: Undefined macros: configure.in:104:AC_PROG_RANLIB ..... rebuilding php_config.h.in /usr/local/bin/m4: autoheader.m4: No such file or directory ----------------------- Next I issued ./configure --with-stat...but ----- ./configure: Syntax error 4: `AC_INIT' unexpected ---- ANy help ?
