What command outputs this?  Does the library libmylib1.so exist at this
time?

Why are you not using Libtool?  Put AC_PROG_LIBTOOL in configure.ac, run
libtoolize, and use this in Makefile.am:
  lib_LTLIBRARIES = libmylib2.la
  libmylib2_la_SOURCES = s2.cpp
  libmylib2_la_CPPFLAGS = -I../lib1
  libmylib2_la_CXXFLAGS = -Wall -O0
  libmylib2_so_LIBADD = ../lib1/libmylib1.la

You can then drop the libmylib2_so_DEPENDENCIES setting, too.

Cheers,
