I have a similar directory structure to that one in my ~/src/ocaml/my
directory.  As far as lib/ and libsrc/ go, it's exactly the same.  Rather
than having a src/ directory, though, I'm not going to use a toplevel
Makefile and instead have my projects in their own directories at the same
level as lib/ and libsrc/.  Of course, I only have one project at the 
so it's not a huge deal, but when I get more it might matter :)

All the lib/* directories compile and install correctly using the following

OCAMLMAKEFILE = ../../OcamlMakefile

RESULT = a.out
LIBDIRS = ../../lib
INCDIRS = ../../lib
LIBINSTALL_FILES = *.mli *.cmi *.cma *.cmo *.cmx *.cmxa *.a *.o

all:	byte-code-library native-code-library


Everything works correctly *except* that after I make libinstall, it removes
the *.mli files from the directory, which I don't want it to do.

I do get hung up, however, when trying to compile my project, using this

OCAMLMAKEFILE = ../OcamlMakefile

SOURCES = calc_parser.mly calc_lexer.mll
RESULT = ircbot
LIBS = unix pcre
LIBDIRS = ../lib
INCDIRS = ../lib

all:	byte-code native-code


Everything compiles correctly, but when it gets to the linking stage, it 
me this:

gmake[1]: Entering directory `/usr/home/jfincher/src/ocaml/my/ocamlbot'
ocamlc  -I ../lib      -ccopt -L../lib  unix.cma pcre.cma   -o ircbot \
                        calc_parser.cmo calc_lexer.cmo ircmsg.cmo irclib.cmo 
ircutils.cmo logger.cmo flusher.cmo ircusers.cmo factoids.cmo help.cmo 
privmsg_callbacks.cmo callbacks.cmo irctester.cmo
Error while linking ircmsg.cmo: Reference to undefined global `Py_string'
gmake[1]: *** [ircbot] Error 2
gmake[1]: Leaving directory `/usr/home/jfincher/src/ocaml/my/ocamlbot'
gmake: *** [byte-code] Error 2

And I have no idea what to do about it.  All the proper* files 
in the lib directory as they should be.

Any comments on the above Makefiles, either related to my specific questions
or not, are appreciated.
