Thanks for the bugreport including fix. Fix was not complete,
I added the missing changes for manual config.

• Depend on acroread7 instead of acroread5. Acroread5 is outdated and marked BROKEN due to multiple security issues So the port didn't build/install
• changed manual config and batch mode
• portrevision bump
