best,

The unix VMs in this build are defunct.  The UnixOSProcessPlugin was broken.  Please find functional ones in http://www.mirandabanda.org/files/Cog/VM/VM.r2562.

Add -blockonerror flag to Unix & Mac VMs to allow attaching gdb on
error/segv.

Cool!! Thanks, Eliot

I assume they don't include the FilePlugin changes?
Because then they will only work under Pharo 1.4 and before!

In Pharo 2.0 we make heavy use of
        <primitive: 'primitiveDirectoryEntry' module: 'FilePlugin'>

since it provides file access in O(1) instead of O(n^2/4) by
  <primitive: 'primitiveDirectoryLookup' module: 'FilePlugin'

however the primitive was completely broken under mac, so we fixed the following
- proper alias resolving
- proper directory lookup

plus we added another entry in the basic array returned from the primitives which
allows us to access the posix permissions (mac / linux / win.

the changes are spread over several commits:
        https://gitorious.org/cogvm/blessed/blobs/history/fdd5230337112db9273ddc3991e598b322a8f1d4/platforms/iOS/vm/Common/Classes/sqSqueakFileDirectoryInterface.m


The VM will still work with older images, however Pharo 2.0 requires a VM with
these primitives properly implemented, since we don't use FileDirectory anymore
and the new FileSystem only uses #primitiveDirectoryEntry.
