‘guix-build’ searches all modules under gnu/packages; in those modules,
it searches all the public variables that match ‘package?’, and finally
compares against their ‘name’ field.

Could it be that your package is not in a public variable?

That’s expected: what matters it the ‘name’ field of the ‘<package>’
instance, not the name of the file that defines it.

Can you provide more details?  It appears to build for me as
/nix/store/2kdr905aj5kkm0mrwjqxsgv6zvmh2y0j-bison-2.6.1 (x86_64-linux).

Actually, there’s an evil bug.  ‘guix-build’ & co. do this:


So if you’ve run ‘make install’ before, the installed modules will
prevail over the non-installed ones.

I’ll see how to fix it.  In the meantime, you can, ahem, run
‘make uninstall’ or ‘make install’...
