Did it always fail without libmono1.0-cil?

A quick check on booc.exe (monodis --assemblyref) only showed System and
mscorlib as references, which are covered by libmono-corlib1.0-cil and
libmono-system1.0-cil.

I suspect either boo is doing something "nasty" (in a dynamical way,
like reflection), or Mono itself does something nasty which boo just
triggers.
At a first look of libmono1.0-cil package content, the
file /usr/lib/mono/1.0/Mono.CompilerServices.SymbolWriter.dll looks like
it could be related to it. All other libraries in that package shouldn't
be used by boo (in some magical way).

I will investigate in the source of boo (I hope it's not written in
boo...)
