pear install Log fails

[Wim Bakker]

Hello ,

I'm trying to install the horde web client , for that some extra's were 
necessary , one of them the Log extension, which needs SQLite.
So I installed the SQLite extension :
-----------------
Build process completed successfully
Installing '/var/tmp/pear-build-root/install-SQLite-1.0.3//kolab/lib/php/extensions/no-debug-non-zts-20020429/sqlite.so'
install ok: SQLite 1.0.3
-------------------------
It says install ok , so I assume , that means it is installed , but when I try
to install next the Log extension , I get the following error :
------------------------------------------- 
root at mailgateway:/kolab/SRC# /kolab/bin/pear install -f  Log
downloading Log-1.9.4.tgz ...
Starting to download Log-1.9.4.tgz (37,443 bytes)
..........done: 37,443 bytes
'sqlite' PHP extension is not installed
Log: Dependencies failed
-------------------------------------------

What is happening here ?
How do I make it clear to the system that the
sqlite extension is actually installed , are there
any configuration changes necessary, and where?


TIA
