This was quick. It was not my intention to put this preassure on you,
I was just stating the facts :-)

Why do you need this library? I am able to load the backends without
this (at least I am not aware of dlcmpat being installed on my system).
What are the symptoms if you don't have this? 

Which frontends are you using? I am having problems with the preview
areas in both Xsane and xscanimage.

I only had to change the endpoint stuff in sanei_usb.c. I can talk to
my scanner and actually start a scan, but the communication hangs when
the scanner expects the acknowledge message after sending the first
batch of data (about 18KB). This is with an EPSON Perfection 600. 
I am using Darwin 10.2.1, and should probably test it with 10.2.2 again.
