automake "internal error" trying to build gpsd

[Rich Wales]

I attempted to build the "gpsd" sources (gpsd.berlios.de) on an OpenBSD 4.6
system, using autoconf 2.61 and automake 1.10.  I'm getting the following:

automake: ####################

The "gpsd" people say they can build their sources just fine and have no real
explanation of why I can't.

What files from the package I'm trying to configure should I look in (or what
would you need to see) in order to track down what is broken here?
