Comment:
From `collects/openssl/libcrypto.rkt`:

```
#lang racket/base
(require ffi/unsafe
         racket/runtime-path
         setup/cross-system
         (for-syntax racket/base
                     setup/cross-system))

         openssl-lib-versions)

;; Notes on shared library versions when provided by OS
;; ie, VERSION s.t. OS provides "lib{crypto,ssl}.{so,dylib}.$VERSION"
;;
;; As of 1.0.0, OpenSSL has adopted a friendlier version policy (see
;; https://www.openssl.org/policies/releasestrat.html), and recent
;; Linux distros (eg Fedora 27, Debian 9.3 ("stretch")) seem to be
;; using (more) compatible .so versions.
;;
;; Notes on older versions:
;; - Debian and Ubuntu use a few fixed library versions even though
;;   actual OpenSSL version changes:
;;   - Debian squeeze: lib{crypto,ssl}.so.0.9.8
;;   - Debian {wheezy, jessie, stretch, sid}: lib{crypto,ssl}.so.1.0.0
;;   - Ubuntu {14.04, 14.10, 15.04}: lib{crypto,ssl}.so.1.0.0
;;   - Debian and Ubuntu also provide versionless library in pkg "libssl-dev"
;; - Fedora provides libraries suffixed with actual versions (eg
;;   1.0.1k) as well as a simply-versioned symlink (eg libssl.so.10):
;;   - Fedora {19, 20}: lib{crypto,ssl}.so.1.0.1e, also lib{crypto,ssl}.so.10
;;   - Fedora 21: lib{crypto,ssl}.so.1.0.1j, also lib{crypto,ssl}.so.10
;;   - Fedora 22: lib{crypto,ssl}.so.1.0.1k, also lib{crypto,ssl}.so.10
;;   - Fedora also provides a versionless library in pkg "openssl-devel"
;; - Mac OS includes 0.9.8, 0.9.7, and versionless, but as of 10.15 the
;;   versionless dylib and will abort with the following error:
;;   "Invalid dylib load. Clients should not load the unversioned libcrypto
;;   dylib as it does not have a stable ABI."

(define openssl-lib-versions

    ([versions

    (case (system-type)
      [(macosx) versions]
      [else
       (case (path->string (system-library-subpath #f))
         [("x86_64-darwin" "i386-darwin") versions]
         [else
          (cons "" ; versionless (eg from devel pkg)
                versions)])])))
```

Might just be a matter of patching this into a semblance of reasonability.
