ah.

libgyachi is defined in the Makefile.am (attached) as follows:

gyachilib_PROGRAMS = libgyachi.so

gyachilibdir = @libdir@

libgyachi_so_SOURCES =  gytreeview.c gytreeview.h \
	.
	.
	.

and ...

now that you mention it, I think I understand what's happening. I was using a _PROGRAMS as
opposed to a _LTLIBRARIES.

I'm mostly all set now.

Remind me again, what is the purpose of the ".la" file. If my package's .so file is not
intended to be linked against, then i believe that there is no point to distribute the
".la" file, correct? (la is "link archive" I think).
