how to force installation of debian package

[Jan Brosius <jan.brosius@skynet.be>]

Hi,

I am using sidux os (sid debian). I have compiled maxima from source with sbcl 
since this works and the debian maxima package compiled with gcl doesn't 
work.
Now I want to install the debian package wxmaxima that needs maxima to work 
properly. But I can not install this package since it proposes to install 
also the faulty debian maxima package. 

Is there any posibility to install the wxmaxima package without installing the 
faulty maxima package?

Thanks for any help
Jan
