[Voyage-linux] How do i compile mISDN with kernel source?

[lizhong zhu]

hello, users:
i download the 0.5 version and want to compile the mISDN but the system needs kernel source. the error is:
make: *** /lib/modules/2.6.23-486-voyage/build: No such file or directory. 
there is no build for compiling the mISDN, the system needs to get the source. 
but i can not get it. the error is:
voyage:/usr/src/mISDN-1_1_8# apt-get install linux-source-2.6.23-486-voyage
Reading package lists... Done
Building dependency tree... Done
Package linux-source-2.6.23-486-voyage is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package linux-source-2.6.23-486-voyage has no installation candidate
i think it is a big weakness of voyage-linux for compiling some software from source.  how can i get it ? please give me a hint. 
regards!
