LF: OSX 10.1.5 driver for LinkSys 100TX USB Ethernet Adapter

[idallen]

The Pegusus USB 1.1 software for 10.3 works fine under 10.4 with this adapter (I tried it on a 10.4 machine):

But I only have a 10.1.5 machine.  Anyone able to build this adapter for 10.1.5?

Lightning fried the Ethernet port on this 600Mhz iMac Graphite a few weeks ago.
A new motherboard will be circa $500.  OSX 10.4 wil be $150.  I'm hoping to
avoid all that if I can just get this driver built ...
