Rick:

Your assumption is correct; set up lirc for a Hauppauge PVR-x50 card.  The 
lirc driver you need is the I2C driver, NOT any kind of USB driver.  The 
actual IR receiver is an I2C chip inside the PVR USB2 device itself; the 
pvrusb2 driver exports an I2C adapter interface to the kernel through 
which the lirc I2C driver will attach an operate the chip.  So from the 
viewpoint of lirc this is all I2C and the USB aspect of the device is 
completely invisible to it.

I probably should add a clarification about this.  It never even occurred 
to me that the fact that the PVR USB2 device is a USB peripheral that 
there might be some confusion here.

As for the other issues you hit with compiling lirc, I can't suggest much 
there.  I've been running lirc 0.7.0 here on a somewhat older kernel. 
Whatever that problem is must be related to lirc and the kernel and not to 
the pvrusb2 driver itself.  But, if you do get it to compile, it's the 
"Hauppauge" (aka I2C) driver that you want to select.
