I've added xclip as a propagated input for shroud as otherwise `shroud

show --clipboard` functionality didn't work, neither primary or

secondary clipboard.

xclip is about 102 MiB in size, out of which a little more than 60% is

glibc and gcc.

I am not sure if this is the best idea though.

How? 

Snippet from (shroud utils):

;; Instance of use of xclip
(define (call-with-clipboard proc)
  "Call PROC with an open output port to the X clipboard."
  (call-with-output-pipe* (list %xclip "-selection" "clipboard") proc))

;; Use of gpg
(define (call-with-encrypted-output-file file user-id proc)
  "Apply PROC with an output port that writes encrypted data to FILE
for the recipient USER-ID."
  (call-with-output-pipe* `(,(gpg-binary)
                            "--no-tty" "--batch" "--yes"
                            "--encrypt" "--armor"
                            "--recipient" ,user-id
                            "--output" ,file)
    proc))

Thanks,
amar

I also looked at the code and it looks like there's already substitution
in place to record the locations of xclip and gpg. Perhaps you're trying
to paste from the wrong clipboard? "clipboard" indicates that "Control + V"
should work for pasting.
