Hi Stephan,

Wow, what a useful webpage! I wish it was linked to from

Now, reports from the field.

I ran the install script, modified the export script to only export
:dependencies, and ran it like

./export redwoods/jun-04/vm6/04-06-11

(after fiddling with LD_LIBRARY_PATH to make libXm visible) on a recent
Fedora machine with 500m of RAM.

The result:

[changing package from "COMMON-LISP-USER" to "LKB"]
LKB(1): Error: An explicit gc call caused a need for 532938752 more bytes
       heap.  The operating system will not make the space available
       because of a lack of swap space or some other operating system
       imposed limit or memory mapping collision.

Well, I said, fine.  I'll find you more memory.  I installed on one of
stanford's vine machines (2GB ram, debian 3.0).
a) uname does not understand -i on this machine.  I created a wrapper.
b) libc against which libXm is linked is different from libc on this
machine.  bomb.

Well, I said, fine.  I'll give you a Solaris machine.  So I installed on
on one of Stanford's tree machines.  After chaning export to run the
solaris tdsb, i got it to churn for a while, until it bailed with

But it did get up to

exporting `redwoods/jun-04/vm6/04-06-11' [4000 -- 4200]

before then, so may be the output is lying around somewhere?  If so,
