Please split these two into separate patches.

Please use gexps and #$output here:

  (replace 'install
    (lambda _
      (let ((lib (string-append #$output "/lib")))
        (mkdir-p lib)
        (copy-file "target/release/libtsc_dyn.so"
                   (string-append lib "/tsc-dyn.so")))))

This ``version'' and ``source'' are unnecessary.

LIST, please.

Gexp this, please.

Please use #$output.

The leading / is redundant; this will do:

  (search-input-file inputs "lib/tsc-dyn.so")
