[ESS] Cannot open load file: executable

[Heinz Tuechler]

Using Xemacs version 21.4 - April 2001 I had no problem until I updated the
installed packages.
Now I receive the error message:
(1) (initialization/error) An error has occurred while loading
d:\xemacs\.xemacs\init.el:

Cannot open load file: executable

To ensure normal operation, you should investigate the cause of the error
in your initialization file and remove it.  Use the `-debug-init' option to
XEmacs to view a complete error backtrace.

I have very little experience with Xemacs, therefore my question is:
How do I " Use the `-debug-init' option"?
more precisely
Where can I find a documentation that explains how to invoke this option.


Just in case, someone wants to comment on the error, here is more information.

Since I am using the identical init.el-file I don't think that the error
has to do with this file.
After some experiments I suspect that it could have to do with the file
essd-sas.elc.

For the next days I will have little access to the internet, so please
excuse me if I do not respond immediately. This is also the cause why I did
not search a lot in archives.

Thanks in advance
