denemo starts with an error

[Bernhard Rueckerl]

Hello,

I have just installed Edgar's package of denemo on my OpenSuse Leap 15.4
When I start it from the command line as

denemo ( without any arguments )

I get the error-message:

ERROR: Unbound variable: eval-when

I use guile 3.0

I did not find anything in the Mail-Archive about this error. How can I 
avoid it ?

regards
