Do you have to load an optional package or is this support enabled
What Linux packaging format can you load?
Instructions for using the Linux binaries on FreeBSD would be
better from a maintenance viewpoint. Plus short term, it is
all that is going to happen. Could you provide a few paragraphs
for the Getting Started manual detailing this?

<sigh> YAPF - Yet another packaging format <sigh>. The 1st cut
at Sun binaries are RPMs and .tgz's produced by Alien. Rewriting
package descriptions in a lot of odd packaging languages is time

I think BDM is important to support. If Eric Norum can't
use the gdb RPM, then who can? :)
We started to add the BDM patch but had to stop and
back it out because there were problems that were too
complicated to address this close to a release.
The problem is that the BDM patches are Linux specific,
not enabled for m68k-rtems, and do not turn themselves
off when configuring on a non-Linux host.
As it is, this causes problems building for non-Linux hosts.
Moreover, you have to have the bdm device installed to use it.
Mostly I think it is a matter of tinkering with configure
scripts in gdb so:
+ disable automatically on Linux
+ m68k-rtems on Linux includes this bdm support
+ m68k-rtems on other hosts does not include it
+ address the device installation issue
+ address including bdm documentation in the RPM.
Overall, it probably isn't very much but it needs to be
addressed. The first few are improvements to the
BDM patch, the latter ones are RPM spec issues.

Starting out with the "Linux binaries on FreeBSD" insrtuctions will
help out some if they really can be used.
After that, I suppose real pkg descriptions need to be generated. If
you can figure that out, it would be appreciated. This is similar to
how David Fiddes figured out the Cygwin situation and OAR is trying to
take over the procedure and generate them regularly.
