sage 8.9beta4 ntl

[Han Frederic]

Hello,

I have something strange (fedora 29, amd64)

I have cloned sage 8.9beta4

and make it. All seems functionnal but I realised that ntl is not built. This looks strange because giac is built and ntl is listed in the file:

build/pkgs/giac/dependencies

Moreover I have ntl and other giac deps from fedora and now the system ntl is used.

(sage-sh) fred@localhost:sage$ ldd local/lib/libgiac.so
    linux-vdso.so.1 (0x00007ffc4ffc2000)
    libntl.so.38 => /lib64/libntl.so.38 (0x00007f312e038000)
    libpari-gmp.so.6 => /home/fred-dev/sage/develop/sage/local/lib/libpari-gmp.so.6 (0x00007f312d791000)
    libgsl.so.23 => /home/fred-dev/sage/develop/sage/local/lib/libgsl.so.23 (0x00007f312d50e000)

I don't think it happened on sage 8.8.

Can you reproduce this?

Well, this is how it is meant to be!
See https://trac.sagemath.org/ticket/27330

E.g. if you have a compatible NTL installed, it will be used instead
of a vendored version.

in fact, https://trac.sagemath.org/ticket/27822 was already in 8.8
and system NTL is already usable there. But you need to rebuild from scratch
or, at least, expicitly uninstall Sage's NTL (and rebuild) to use the
system NTL.
