Impossible to install CLISP onto ARM running Debian

[Jean Marangos]

Dear Sir or Madam,
though present in the lenny(stable) repositories, it is not possible to 
install CLISP onto an ARM processor running Debian via either "aptitude" 
or "synaptic" as suggested in the "Download Page for 
clisp_2.44.1-4.1_arm.deb on ARM machines". Both package manager are able 
to find other packages e.g. "clisp doc, clisp-dev, slime, etc.  ....." 
but not CLISP itself. The problem persists even when using "apt-get 
install clisp/stable".
I would very appreciate to obtain support for resolving this issue.
Thank you,
Jean
