Tutorial problem install postfix over Fedora 15

Hello friends:

I'm installing Postfix with this howtoforge tutorial:

http://www.howtoforge.com/virtual-u...urier-mysql-and-squirrelmail-fedora-15-x86_64

I want to install all e-mail system in stock Fedora 15 installation, but I have problems in step "rpmbuild -ba postfix.spec":

# rpmbuild -ba postfix.spec
....
....
ATTENTION:
ATTENTION: Unknown system type: Linux 3.2.13-grsec-xxxx-grs-ipv6-64
ATTENTION:
make: *** [Makefiles] Error 1

Please, anyone can help me with this error?. Prior steps is all OK.

Thanks!!

 

Is this a standard Fedora 15 installation with a standard Fedora 15 kernel?

 

I was think yes, but today I know that this Fedora 15 have OVH server kernel.

Can I repair the error if I have other kernel version?.

Thanks!!

 

I guess it will work with a standard Fedora 15 kernel (at least it did for me).
