Guile 2.2.0 build fails at bootstrapping language/cps/types.go

[白い熊]

Hello:

I'm trying to build the new GNU Guile 2.2.0 - my build fails eventually 
with:

make[2]: Leaving directory 
'/home/shiroikume/compile/guile-2.2.0/libguile'
Making all in bootstrap
make[2]: Entering directory 
'/home/shiroikume/compile/guile-2.2.0/bootstrap'
  BOOTSTRAP GUILEC language/cps/types.go

make[1]: Leaving directory '/home/shiroikume/compile/guile-2.2.0'

make: *** [all] Error 2

I haven't found anything on the web similar to this. How can I debug 
what's going on - why it's failing?
