There's no problem, as long as you distribute your program under the GPL,
which means providing the source on demand to anybody to whom you distribute
a binary.

If you want to distribute under another license, then it comes down to how you
developed the code.  If you developed the code to work similarly to tail, but
you did not use any tail code (or any other GPL code) directly, then you're
pretty much free to use any license you like.  However, if you started off
with the tail codebase and altered it, it is a derivative work, and GPL is the
only way to go.
