Description

Hi, since arrow 4.0.0 I'm having trouble getting the lz4 codec installed on ubuntu 20.04. After installing arrow 4.0.0 via CRAN, I run 

install_arrow(binary = FALSE, minimal = FALSE) 

After this completes, then

arrow_available()
[1] TRUE

codec_is_available("lz4")
[1] FALSE

What can I do to help resolve this problem?
