Mandraker,

Thanks.

This was due to ...unconventional shebang usage upstream:

 #!/bin/sh 
 # \
 exec wish "$0" "$@"

I don't pretend to comprehend why.  I don't see any polyglottal 
cleverness going on below it.

Our built-in ‘patch-shebang’ has no problem patching first one 
(creating a bogus dependency on bash, now gone) but can't see the 
obfuscated wish one.

Fixed[0] by turning it into a proper shebang first.

Please test and report your results; it complains about a missing 
configuration file here.

> xbindkeys_show use the package Tk that is not declared

They do declare it, kind of, in xbindkeys.spec and ./configure 
etc.  And (incidentally) halfway down the ChangeLog file.  Hardly 
obvious, indeed.

Kind regards,

T G-R
