Trying to install Parallel Tools on Gentoo

gcc has an error compiling prl_eth/pvmnet

"/usr/lib64/parallels-tools/kmods/prl_eth/pvmnet/pvmnet.c:194:3: error: 'struct ethtool_ops' has no member named 'get_settings'; did you mean 'get_strings'?"

does anyone know what this means?

This use to install fine before I did some package updates...

-- below is the full error on install...

Code:

I also met the same problem and just fixed it. Hope my solution can help you.
This problem is caused by ethtool deletingthe member variable ".get_settings" of struct ethtool_ops. So we just need to delete ".get_settings = pvmnet_get_settings,".
More specific steps are as follows:

Code: 
> cp -r /mnt/cdrom ~/tmp
> cd ~/tmp/kmods
> tar xvf ./prl_mod.tar.gz
> vim prl_eth/pvmnet/pvmnet.c

| and replace the line (or just delete the line)
|------------------------------------------------------------
| 	.get_settings = pvmnet_get_settings,
|------------------------------------------------------------
| with
|------------------------------------------------------------
| #ifndef ETHTOOL_GLINKSETTINGS
| 	.get_settings = pvmnet_get_settings,
| #endif
|------------------------------------------------------------

> tar -zcvf prl_mod.tar.gz ./ dkms.conf Makefile.kmods
> cd ~/tmp
> ./install --install
