Odd. I hope it's still possible to set DYLD_LIBRARY_PATH to a valid
absolute name of a directory?

I think a reasonable way is to add
abs_top_builddir = @abs_top_builddir@
TEST_SHLIB_DIR = "${abs_top_builddir}/.lib"
to config.make.in, and use that to set LD_LIBRARY_PATH. And possibly
only pass TEST_SHLIB_DIR to the run-tests script, and move the logic to
setup the environment.

Not the test programs, but the programs in tools/ are, and they're also
run by the testsuite.

It's used by LSH_RPATH_FIX, just after the check for gmp.
: # Checks for libraries
: if test "x$enable_public_key" = "xyes" ; then
: if test "x$enable_mini_gmp" = "xno" ; then
: AC_CHECK_LIB(gmp, __gmpn_sec_div_r,,
: [AC_MSG_WARN(
: [GNU MP not found, or too old. GMP-6.0 or later is needed, see
: https://gmplib.org/.
: Support for public key algorithms will be unavailable.])]
: enable_public_key=no)
:
: # Add -R flags needed to run programs linked with gmp
: LSH_RPATH_FIX
: fi
: fi
This is intended to handle the case that gmp is in /usr/local, you
configure with --with-lib-path=/usr/local/lib
--with-inlcude-path=/usr/local/include, but the runtime linker doesn't
look in /usr/local/lib. Then LSH_RPATH_FIX will add the appropriate
flag to set rpath. (I see there are some other unused macros in
aclocal.m4, left overs from when nettle was taken out of lsh).
