["Uwe Korn (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-6766?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16973663#comment-16973663 ] 

Uwe Korn commented on ARROW-6766:
---------------------------------

As you install in a non-standard location, you probably also need to adjust the pkg-config search path. Try setting {{PKG_CONFIG_PATH=$(pwd)/arrow/dist/lib/pkgconfig}}.

> What is quite strange is that the libraries seem to indeed be there but they
>  have an addition component such as `libarrow.15.dylib` .e.g:
> {{$ ls -l libarrow_python.15.dylib && echo $PWD}}
>  {{lrwxr-xr-x 1 tallamjr staff 28 Oct 2 14:02 libarrow_python.15.dylib ->}}
>  {{libarrow_python.15.0.0.dylib}}
>  {{/Users/tallamjr/github/arrow/dist/lib}}
> I guess I am not exactly sure what the issue here is but it appears to be that
>  the version is not captured as a variable that is used by CMAKE? I have run the
>  same setup on `master` (`7d18c1c`) and on `apache-arrow-0.14.0` (`a591d76`)
>  which both seem to produce same errors.
> Apologies if this is not quite the format for JIRA issues here or perhaps if
>  it's not the correct platform for this, I'm very new to the project and
>  contributing to apache in general. Thanks
