kgio 2.5.0 failed build/install

Hi,

Seeing this on CentOS 5.6:

### build error

Building native extensions.  This could take a while...

No such issues on my Ubuntu/Scientific Linux 6/CentOS 5.5 boxes. Any
clues what could be the reason ?

Tried a different ruby build ( same version though - 1.8.7 ! ) - one
using rvm and one from this repo:
http://centos.karan.org/el5/ruby187/$basearch/

With the rvm ruby, kgio compiles fine on this box, as well.

Weird, clock_gettime() and poll() aren't detected, either.  Those
should always be present in a Linux system.

It could be a mixed 32/64-bit environment problem.  Can you verify
your gcc/Ruby are 64-bit?

The mixed 64-bit/32-bit toolchain is the only thing that comes to
mind.

I've always built my own Ruby packages (since long before RVM) on
CentOS/Debian machines.  Those distros enable pthreads by default on 1.8
(for tcl/tk compatibility) and that kills performance.  If RVM works for
you, then go for it, otherwise "./configure --prefix=$HOME/foo && make
&& make install" works great, too.

I couldn't really find the exact problematic libs, but starting again
from scratch taking close care of the arch libs - seems to make it
work fine.
Thanks for the hint !
