libc.so.4

[Fam. Engelen]

I recently came across a program (for which I have not found the source code, though it may be available) which seems to depend on libc4 (it gives the error message 'file libc.so.4 not found' or similar). There is no Debian package for slink containing this library, as there is for libc5. Does this mean I cannot use this program? Where would I be able to find libc.so.4? Would it hurt just putting it in /lib/?   Any response is appreciated   Arnout [EMAIL PROTECTED]
