Hello Nobuhiro,
this problem occured in version 2~rc1-1 of mathgl which has been uploaded to 
experimental. I have created a patch there that fixes this build failure for 
the 2~rc1-1 version.

Version 1.11.2-6 builds fine in the official architectures of sid as far as I can 
see. 

Anyway, I plan to upload new debian versions for both 1.11.2 and 2~rc1 soon, 
so I will check how thing go.

Thanks for your work for mathgl
Dimitris
