Hi Marijn,

Sorry for the late response.  Comments bellow.

The problem seems to be related to environment variables clash.

Both chicken's rules.make and Portage uses the `O' variable which
seems to be causing the problem.

Here's the error message I get:

  Assembler messages:
  FATAL: can't create library-static/usr/portage/dev-scheme/chicken: No such 
file or directory
  make[1]: *** [library-static/usr/portage/dev-scheme/chicken] Error 1
  make[1]: Leaving directory 
`/var/tmp/portage/dev-scheme/chicken-2.732/work/chicken-2.732'
  make: *** [all] Error 2

Here's the corresponding snippet from rules.make:

  $(C_COMPILER_BUILD_RUNTIME_OPTIONS) $< $(C_COMPILER_OUTPUT_OPTION) 
address@hidden(O): library.c chicken.h $(CHICKEN_CONFIG_H)

Here's the relevant snipped from the execution of `env' from the
ebuild file:

   O=/usr/portage/dev-scheme/chicken

So, it seems that the O value from the environment is being passed to
make, which concatenates "library-static" and
"/usr/portage/dev-scheme/chicken".

Hope this helps.

Best wishes,
Mario
