Could not load Xwt.Mac.ListViewBackend from Xwt.Mac 0.1.0.0 (4c990b20)

[Taryn Hill]

Hi all, with these commits (the latest afaict) I get the below error:

xwt: 4c990b204468dd187d38bf88933e659dee86fb80
monomac: 1d878426361aea31f9e31b509783703fbd797c8c
maccore: ef6a975d648137cad41050d11493a7820a28f93a

"Could not load type 'Xwt.Mac.ListViewBackend' from assembly 'Xwt.Mac, Version=0.1.0.0, Culture=neutral, PublicKeyToken=null'."

The particular code causing this is here:
https://github.com/SirCmpwn/TrueCraft/blob/9ca7bcabca431bb0a109d80c736bcf0db55059c1/TrueCraft.Launcher/Views/OptionView.cs#L89-L95

The assembly browser shows me that that type does indeed exist in the Xwt.Mac.dll assembly:
(image above, this interface refuses to let me put it anywhere else)

What am I doing incorrectly?

Thanks for your time,
Taryn
