[PHP 5.2.9] make test fail, how important is it?

["Jean-Yves G." <vcofe@xxxxxxx>]

Hi there,

I'm trying to compile php on my own, but i'm facing some issues...

PHP version : 5.2.9
OS: Ubuntu 9.04 64bit

I've compiled php with :
../configure --enable-debug --enable-fastcgi
make all test

the "make test" ended with this result :

How much do i need to care about this failed test ??
Are there any critical failure ? how to solve them ?

I'm a bit lost, and i hope someone can give me some informations to get 
it sorted.
Any help is much appreciated.

Thanks

Jean-Yves
