[Clojure] mxnet-scala cannot be loaded without legacy openssl

[cbowdon]

Description

I have a very similar (probably related) issue to #12822 when using the pre-built jar. Same error message as @kohr-h describes, except instead of the unsatisfied link being libcurl3 it is libcrypto.so.1.0.0. It turns out this is provided by libopenssl1_0_0 which is again a package that I do not want to install system-wide to avoid breaking other things.

Error Message:

Minimum reproducible example

1. Create deps.edn with this content:

{:deps {org.clojure/clojure {:mvn/version "1.10.0"}
        org.apache.mxnet.contrib.clojure/clojure-mxnet-linux-cpu {:mvn/version "1.3.1"}}} 

Steps to reproduce

1. clojure
2. (in REPL) (require '[org.apache.clojure-mxnet.ndarray :as ndarray])

What have you tried to solve it?

I've located the missing library (see description). The workaround described in #12822 should be fine, but as stated in that issue it would be better if there wasn't a dependency on legacy packages in the first place.

@lanking520 @frankfliu can you please comment on this issue?

[lanking520]

@cbowdon Thanks for filing this issue. Please try to use our latest 1.4.0 package, it is statically linked most of the dependencies together.

[piyushghai]

@cbowdon Were you able to test it out on the v1.4.0 Scala jar from Maven ?

[cbowdon]

@piyushghai I haven't yet found time I'm afraid. If you'd like to close the ticket and let me re-open it if 1.4.0 doesn't work that's fine by me.

[lanking520]

@cbowdon Yeah, please reopen if 1.4.0 doesn't work
