[Tuxaloosa] VBox on slackware

[E Hanson]

i'm having a little trouble getting VirtualBox on the new Slackware 
(12.2). i've tried a SlackBuild with the source. and i've tried 
./configure, make, make install on the source and both give me the 
following output after unpacking:
patching file VBox.sh
/tmp/SBo/VirtualBox-2.0.6
Checking for environment: Determined build machine: linux.x86, target 
machine: linux.x86, OK.
Checking for kBuild: found, OK.
Checking for gcc: found version 4.2.4, OK.
Checking for as86: found version 0.16.17, OK.
Checking for bcc: found version 0.16.17, OK.
Checking for iasl:
  ** iasl (variable IASL) not found!

and then it exits.

google tell me that iasl is an intel compiler. part of the acpica 
package. acpica.org has unix source code, but also says that the linux 
kernel >2.4 has it built in, and that the linux versions of the 
user-space ACPICA utilities (iASL, AcpiExec, AcpiXtract) can be built 
from the UNIX ACPICA source code package.
so i got the package and built iasl (in the compiler/ dir) with make, 
and it built just fine... but i don't know how to install it. i can run 
it from the compiler directory. should i just move the contents of the 
compiler/ directory to a directory in my $PATH? do i need to buils ALL 
of the tools or can i make do with just the iasl?
