Perl Modules

[Antonios Hadjigeorgalis]

Ubuntu 16.04 installs this long list of perl modules when it installs
GnuCash from the repo.  I don't see this documented anywhere (except for
libfinance-quote-perl module).  The build instructions don't mention
these.  Should these be installed when building GnuCash?  If so, I would be
happy to update the wiki build instructions.

The build does succeed without them.
