'NONEXISTENT/charsets/ AND recompiling altered module

Hi, here is the result of a execution of a script via command line. File 'NONEXISTENT/charsets/?.conf' not found (Errcode: 2) Character set '#30' is not a compiled character set and is not specified in the 'NONEXISTENT/charsets/Index' file so, PHP must be recompiled to make it know here charsets are for mysql. I am using precompiled package ıf mysql on my Sarge system, also it is unofficial, so I have not headers or development package. so --with-mysql=bla bla is not working at the moment for me, I have to use bundled one. I decided to change source of mysql extension, the NONEXISTENT word is written on just one file and it is my_config.h. I have changed "NONEXISTENT" to "/usr/share/mysql" and used make clean make make install (no config change is needed but tried with reconfiguring also.) Nope, I simply does not work, php -f test.php still gives me the same charset error... Do you have any advices for me ? regards
