Thanks for the pointer. I tried that, but unfortunately it didn't help. The
error is the same as before.

rebaseall apparently did run:

$ ll /var/cache/rebase
total 375K
-rw-r--r-- 1 ASchulma Domain Users  115 Apr 29 10:27 fullrebase.done
-rw-r--r-- 1 ASchulma Domain Users  35K Apr 29 10:29 rebase_all

-rw-r--r-- 1 ASchulma Domain Users    0 Jan  1  1970 rebase_user_exe.old

And dllunix.so does seem to have been rebased:

$ grep dllunix /var/cache/rebase/rebase_all
/usr/lib/ocaml/stublibs/dllunix.so

$ rebase -i /usr/lib/ocaml/stublibs/dllunix.so
/usr/lib/ocaml/stublibs/dllunix.so        base 0x0003eff30000 size
0x0004b000

But still every ocaml run fails with

Error: Error on dynamically loaded library:
/usr/lib/ocaml/stublibs/dllunix.so: flexdll error: cannot relocate
RELOC_REL32, target is too far: 0xfffffffc0f997112  0xf997112

Any other ideas for how I can get ocaml to work?

Thanks!
