Build fails with the latest commit but works with tag v1.5

[namehta4]

Hi All,

Just wanted to point out that the build fails for me in a container when compiling using the listed steps at

make install

with the following error:

************* TESTS COMPLETED SUCCESSFULLY ****************
make[1]: Leaving directory '/opt/num/test'
make -C src install
make[1]: Entering directory '/opt/num/src'
cp META.top META
ocamlfind install num-top META num_top.cma num_top_printers.cmi num_top.cmi
Installed /usr/local/lib/ocaml/4.13.1/num-top/num_top.cmi

rm -f META
install -d /usr/lib/ocaml
cp META.num META
ocamlfind install num META
ocamlfind: Package num is already installed
 - (file META.num already exists)
make[1]: *** [Makefile:160: install] Error 2
make[1]: Leaving directory '/opt/num/src'
make: *** [Makefile:13: install] Error 2

This behavior is not seen when building with v1.5
