Re: Custom 'install phase

[Julien Lepiller <julien@lepiller.eu>]

I think you need to remove the apply, but keep one level of parenthesis, like so:

((assoc-ref …) args …)

Apply takes the last arguments, which must be a list and appends all its elements to the invocation. Like (apply foo '(1 2 3 4)) is tge same as (foo 1 2 3 4). Here you're probably confused because of the assoc-ref is not a procodure, but it's fine: it returns a procedure, so guile can execute it and pass arguments to it the normal way.
