The installation went well, but when I start the game I get the following message: WinSock IPX bind failed.
I managed to fix this to run the game from the "Run a windows command" option in the Crossover Games menu.
You need to select the executable followed by -noipx. See below for an example.
"/home/<myusername>/.cxgames/Hexen 2/drive_c/Hexen II/h2.exe" -noipx
