Kouhei Sutou commented on ARROW-14076:
--------------------------------------
Thanks.
It seems that absolute link path isn't suitable for Heroku.
I'll re-implement extpp gem as header only library. Then we don't need to link
to {{libruby-extpp.so}}.
FYI: {{libruby-extpp.so}}'s path is detected by here:

> Hello,

> I am not able to get the Ruby gems, `red-arrow` and `red-parquet`, to work
> properly on Heroku. Heroku itself is merely an Ubuntu 20.04 LTS (focal)
> container so this really is a question about what dependencies must be
> installed to get these gems to work on Focal?
> So far I have specified the following in Heroku's `Aptfile`:
> {code:java}
> # Get Heroku's Ubuntu distro for your Stack. Heroku-20 = focal
> # Running bash on ⬢ <app_name>... up, run.1471 (Hobby)
> # ~ $ lsb_release --codename --short
