[php-maint] Problems with PHP5 Apache2 module on Lenny

Tue Dec 14 21:56:33 UTC 2010

After hitting this bug 3 times now - and every time having to relearn how to fix it! - here's what the problem is:

My system has two version of libxml2, one in /usr/lib and another in /usr/local/lib. Both are different versions. Only the /usr/local/lib version is installed by ld.conf:

# cat /etc/ld.so.conf.d/libc.conf 
# libc default configuration
/usr/local/lib
#

So the fix - I'm using anyway is to change the sym link thus:

# cd /usr/local/lib/
# ls -l libxml2.so
libxml2.so -> libxml2.so.2.4.28
# rm libxml2.so.2
# ln -s /usr/lib/libxml2.so.2.6.32 libxml2.so.2
# /etc/init.d/apache2 start
Starting web server: apache2.

NFI how the system has got into this state. Still the next time I have to google the answer at least I'll find it. ;)
