New description:
We need to pass -no-undefined to libtool, the proper place is in
libgap_la_LDFLAGS, potentially only on Cygwin and other Windows systems
(have a look in GMP/MPIR/MPFR for examples), but should not hurt anyway
elsewhere if added unconditionally.
(By the way the spkg-install script is terrible, does not use $MAKE, use [
] and [[ ]], sets CXXFLAGS but does not export it...)

Comment:
I've made a new spkg that includes the `--no-undefined`. Please let me
know if it fixes things.
