[Samba] samba-4.5.1 build problem

[Peter Serbe]

Dear Samba experts, 

I tried to install the latest Samba release the way I 
did it always, i.e. starting with:

./configure --prefix=/usr/local/samba \
            --with-piddir=/usr/local/samba/var/run \
            --with-syslog \
            --with-quotas \
            --with-acl-support \
            --enable-debug \
            --enable-cups \
            --enable-selftest \
            --with-ads \
            --with-shared-modules=idmap_ad

But after a short while this stops throwing an error, 
which is totally cryptic to me

Checking for perl 5.0.0                                                           : ok 5.24.1

What should I do to overcome this?
