[conspire] cannot execute binary file

[Paul Zander]

Tony,
I understand that I did not give a comprehensive set of details.  If you have read the postings to the conspire list, you will see that my problem was rather simple.

OK, a more complete example, then.

What arch? [1]
Download the tarball [2]
Check out the tarball [3], notice it is making a *subdirectory* named firefox
Unpack the tarball[4]
Locate the executable[5]
Verify permissions[6], notice it is owned by me and executable by owner
Run the executable explicitly[7]
Make yourself a symlink so you don't have to give it explicit path[8]

details follow

note that I check and verify my assumptions along the way.  the
assumption that seems to be biting you is that $HOME/firefox is an
executable
