That's GNU bc.  Its -c dumps its internal byte code rather than dc code
because it nevers runs dc.

That's correct output.  The <12> is ASCII FF and is the name of the l()
function as defined by the dc code in bc's -l maths library.

There's your problem.  When your plan9/bin/bc is given -l, it produces
dc to print ‘cannot open input file:1, ’.  Looks like the installation
is incomplete or the file is present but in the wrong place.

At a guess, have you a /usr/lib/plan9/lib/bclib?
