Then another thought; use '--ignorearch' with the FreeBSD rpm command. This seems to install linux apt as required! :o) Maybe this is the right way t= o go?

As far as I can tell I have the following options: 1) Work out how to make RPMs work as discussed above. Would like this anyway to be able to use more linux stuff. 2) Install linux_devtools from ports - but: /usr/ports/devel/linux_devtools % make =3D=3D=3D> linux_devtools-8.0_3 is only for i386, and you are running amd64. 3) Find a tarball of the GCC toolset for RH8 i*86 and extract it into /compat/linux 4) ? Any others ? > For linux64, well first step is to get binaries working >=20 I will just be happy to have 32-bit working for now!
