I just tested building Slony 1.2.13 and PG 8.3.0 on MacOSX 10.4 (PPC).
I had a minor error building slonik:

gcc -I/fink/include -Wall -Wmissing-prototypes -Wmissing-declarations  
-I../.. -DPGSHARE="\"/fink/share/postgresql/\""  \
   slonik.o dbutil.o parser.o  ../parsestatements/scanner.o -L/fink/ 
lib/ -L/fink/lib/postgresql/ -lpq   -lpgport  -o slonik
/usr/bin/ld: table of contents for archive: /fink/lib//libpgport.a is  
out of date; rerun ranlib(1) (can't load from it)

Running ranlib as suggested:    ranlib /fink/lib/libpgport.a      
solves the problem.

I don't know why this happens. With Slony 1.2.12 I haven't seen this  
problem with libpgport.a.
Anyway, it works fine now.  Many thanks to the team.
