Devel.dyne is downloadable via download link at dyne website. Here is
direct link : ftp://ftp.dyne.org/dynebolic/modules.
Kernel source downloaded with command #dynesdk makesdk (because i can't
compile it with kernel-src.dyne)

Don't forget to link your build environment to kernel source, example :

#cd /lib/modules/[kernel ver]
#ln -s /dyne/SDK/modules/kernel-src-2618ck1d/src/linux-2.6.18-ck1-dyne build
#ln -s /dyne/SDK/modules/kernel-src-2618ck1d/src/linux-2.6.18-ck1-dyne
source

then build as usual.
