thanks bob, that is exactly the problem I'm facing.

now I wonder: if the libtool *.la files contain all information about
the dependencies etc, then shouldn't there be some macro that searches
for that *.la files, gets the dependencies from it, does the compile
and link test and sets up CFLAGS and LIBS to include whatever is necessary?

is there something that works like AC_CHECK_LIB, except that AC_CHECK_LIB 
seems to have no clue about *.la files, so is there some alternative that 
does?
