lnav: Though `xclip` is installed lnav won't allow copying.

lnav version v0.9.0

OS version Ubuntu 18.04.5 LTS

Describe the bug I installed lnav (using the latest deb), as well as xclip (using apt) but it will not copy and if I mark a line and hit c, LNAV will report: ~\~X error: Unable to copy to clipboard. Make sure xclip or pbcopy is installed.

work@Xubuntu18-Srvr-070218:~$ apt list --installed | grep xclip
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
xclip/bionic,now 0.12+svn84-4build1 amd64 [installed]

hostname|xclip will successfully copy my hostname to my middle-click copy buffer

To Reproduce

1. Install LNAV from 0.9.0 deb
2. Install xclip from apt
3. In LNAV mark a line and attempt to copy with c
