Don't know how to build task '/Users/ksss/src/github.com/ksss/mruby/build/host/mrbgems/mruby-bin-mrbc/tools/mrbc/mrbc.o' (see --tasks)

@take-cheeze Could you help me? I'm not familier to mruby's build system. What I should fix?

Seems like this line is removing mruby-bin-mrbc

mruby-require/mrbgem.rake

Line 58 in ff56b56

gems.reject! {|g| !compiled_in.include?(g.name)}

yes, I tried to change this line like below.

 gems.reject! {|g| !compiled_in.include?(g.name) && g.name !~ /^mruby-bin-/ }

but still have errors.

Short workaround is add gem core: 'mruby-bin-mrbc' before mruby-require.(Though somehow test build fails)

It maybe resolved.
Thanks!
