Sebek 2 compile issue

["Rick S." <rsheppar () midnight ecet vtc edu>]

Hello,
Im having a bit of trouble compiling Sebek 2.0.1 for linux. Im using
gentoo with the 2.4.20-r6-gentoo kernel. I have read  the other threads
about this. I have changed the include dir and the  tar varibles in  the
makefile but I am left with an error:

/usr/src/linux/include/asm/hw_irq.h: In function `x86_do_profile':
/usr/src/linux/include/asm/hw_irq.h:213: `current' undeclared (first use
in this function)
/usr/src/linux/include/asm/hw_irq.h:213: (Each undeclared identifier is
reported only once
/usr/src/linux/include/asm/hw_irq.h:213: for each function it appears in.)
make: *** [sebek] Error 1

any assistance would be helpful, thank you.

Rick S.
