Creating ebuild for usbsrvd, not uninstalling correctly

[VPN-User]

I am trying to create an ebuild for usbsrvd (USB Sharing via LAN). The package installs fine, but it does not uninstall the kernel module when unmerging and therefore produces a warning on next install that the file already exists. Here is what I have so far (initscript not done yet):

    unpack ${A}

    cd "${S}/modules/src/tusbd"
    convert_to_m Makefile
    sed -i 's:default:module:g' Makefile
}

src_install() {
    linux-mod_src_install

    dosbin "${S}/usbsrvd"
    dobin "${S}/usbsrv"
}

pkg_postinst() {
    local moddir="${ROOT}/lib/modules/${KV_FULL}/tusbd/"

    linux-mod_pkg_postinst
}

The error I get when re-merging:

I'd really like to contribute this ebuild, eventually for addition to portage but I need your help. I've finished most of it so far, but still the kernel module does not get removed on uninstall of package. That causes warning on re-merge because of file-collision.

Here are the files:

default: 
	make -C $(KERNELDIR) M=$(PWD) modules
#	cp tusbd.ko ..
#	make clean
#	mv ../tusbd.ko ./

clean:
	make -C $(KERNELDIR) M=$(PWD) clean

My guess is that something is wrong with the way the makefile handles the fact that its kernel module (I had to modify the 'default' entry to 'module' in the ebuild to get portage compiling).

Any help appreciated. Otherwise, I'll stop here because the file works for me (despite the warning).[/quote]
