kernel headers mismatch (F15)

[Frederic Muller]

Hi!

On that newly re-installed system from RC3 without testing repository 
enabled I am running kernel 2.6.38.6-26.rc1.fc15.i686.PAE but the 
headers I get are 'only' 2.6.38.5-24.fc15.i686 .

Trying to install the source rpm gives me that:
yum install kernel-headers-$(uname -r).src.rpm
Loaded plugins: langpacks, presto, refresh-packagekit
Setting up Install Process
No package kernel-headers-2.6.38.6-26.rc1.fc15.i686.PAE.src.rpm available

What am I doing wrong?

Thanks.

Fred
