Bug 216187

It would be best to remove the hard dependency for net/pecl-smbclient for two reasons.  First, it depends on an outdated and deprecated version of libsmbclient (3.6.25).  Second, Nextcloud's documentation provides two alternatives that are preferred (see https://docs.nextcloud.com/server/10/admin_manual/configuration_files/external_storage/smb.html)

The first option is to replace net/pecl-smbclient with PHP's smbclient module.  This would probably be preferred because it's a lighter weight solution than installing the entire samba suite.  However, I have not seen a port of PHP's smbclient module in the ports tree.

The second option is install the samba suite as a dependency (or rely on an already installed version of samba) instead of net/pecl-smbclient.  I have tested this and can verify that it works.  I installed samba43 from ports and then manually installed nextcloud 11.0.1.  Nextcloud automatically used the command line client "smbclient" installed by the samba43 port for connecting to SMB/CIFS external storage.  I also remember that the old owncloud 9.0 port allowed this (i.e. if samba was already installed, it would use it), so it should be doable.
