Build fails

[Cojocaru Alexandru]

Hi,
the build process fails, this is the message I get:
;;; Failed to autoload find-newest-available-packages in (gnu packages):
;;; ERROR: Syntax error:
;;; gnu/packages.scm:94:22: source expression failed to match any pattern
 in form (warning (_ "cannot access `~a': ~a~%") path (strerror errno))
ice-9/boot-9.scm:108:20: In procedure #<procedure e638c0 at 
ice-9/boot-9.scm:99:6
 (thrown-k . args)>:
ice-9/boot-9.scm:108:20: Syntax error:
guix/scripts/build.scm:227:13: source expression failed to match any
 pattern in form (report-error (_ "~A: package not found for version ~a~%") 
name version)

(Extra newlines added by me.)

guile --version: 2.1.0

I'm compiling from master.

best regards,
Alexandru Cojocaru
