I think the problem is that the apache are still using the old libraries, i fix it removing manually the old libapr* that apache2 was using (the path who shows ldd) and then reinstall the new libraries.

Hi!

I fix it removing manually the old libraries that I have on /usr/local/lib and apache2 remains using that ones:

[CODE]root@posido:/home/rgarcia# cp -up /usr/local/lib/libapr* libapr/
root@posido:/home/rgarcia# rm -i /usr/local/lib/libapr*
rm: remove regular file `/usr/local/lib/libapr-1.a'? y
rm: remove regular file `/usr/local/lib/libapr-1.la'? y
rm: remove symbolic link `/usr/local/lib/libapr-1.so'? y
rm: remove symbolic link `/usr/local/lib/libapr-1.so.0'? y
rm: remove regular file `/usr/local/lib/libapr-1.so.0.2.12'? y
rm: remove regular file `/usr/local/lib/libaprutil-1.a'? y
rm: remove regular file `/usr/local/lib/libaprutil-1.la'? y
rm: remove symbolic link `/usr/local/lib/libaprutil-1.so'? y
rm: remove symbolic link `/usr/local/lib/libaprutil-1.so.0'? y
rm: remove regular file `/usr/local/lib/libaprutil-1.so.0.2.12'? y[/CODE]

and then reinstall the last version using the aptitude:

[code]root@posido:/home/rgarcia# aptitude install libaprutil1 libaprutil1-dev libapr1 libapr1-dev[/code]

and [B]It works![/B] :D

[code]root@posido:/home/rgarcia# /etc/init.d/apache2 start
 * Starting web server apache2 <[/code]

If it doesn't work, check that you are using the correct apr libraries with

[CODE]root@posido:/home/rgarcia# ldd /usr/sbin/apache2
 linux-vdso.so.1 => (0x00007fffe4123000)
 libpcre.so.3 => /lib/libpcre.so.3 (0x00007f3a303b2000)
 libaprutil-1.so.0 => [B]/usr/lib/libaprutil-1.so.0 [/B](0x00007f3a3018f000)
 libapr-1.so.0 => [B]/usr/lib/libapr-1.so.0 [/B](0x00007f3a2ff59000)
 libpthread.so.0 => /lib/libpthread.so.0 (0x00007f3a2fd3c000)
 libc.so.6 => /lib/libc.so.6 (0x00007f3a2f9b9000)
 libuuid.so.1 => /lib/libuuid.so.1 (0x00007f3a2f7b3000)
 librt.so.1 => /lib/librt.so.1 (0x00007f3a2f5ab000)
 libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f3a2f372000)
 libdl.so.2 => /lib/libdl.so.2 (0x00007f3a2f16d000)
 libexpat.so.1 => /lib/libexpat.so.1 (0x00007f3a2ef44000)
 /lib64/ld-linux-x86-64.so.2 (0x00007f3a3087d000)[/CODE]

I hope it helps.
