It's my understanding that the OP does not want to actually run the
program but merely knows either the file is in the PATH or not.
I guess some-function would be something like :
(use-modules (srfi srfi-1)) ; for any
(define (in-path? f)
(let ((path (string-split (getenv "PATH") #\:))
(make-absolute (lambda (path) (string-append path "/" f))))
(any file-exists? (map make-absolute path))))
