It installed fine for me on Snow Leopard, so maybe it's using something that doesn't exist in Leopard.

​This discussion for BibDesk confirms that mach_vm_round_page was introduced in 10.6.

Can you try with the attached patch against the Portfile and the files directory?

Apparently adding an attachment doesn't trigger a notification mail; can you please try with the attached patch against the Portfile and the files directory?

Applying the patch against the Portfile and the files directory did not solve the problem.
Before attempting the upgrade I performed a port clean --all to start afresh.
The main.log and terminal output are attached to the ticket.

terminal output after applying the patch

[neverpanic (Clemens Lang)]

Missing mach_vm_trunc_page(x) and ProcessPCH fails because it doesn't support -fblocks. I'll try to make a patch for that.

revised patch for darwin9

[neverpanic (Clemens Lang)]

Can you please re-try with the revised patch?

The second patch resolved the issue with the unsupported -fblocks switch.
Now the build fails with some syntax errors.
A new main.log file is attached to the ticket with the details from the build with the second patch applied.

Those syntax errors are caused because HexFiend uses anonymous lambda-style functions introduced with grand central dispatch in 10.6 (see ​https://developer.apple.com/library/mac/#featuredarticles/BlocksGCD/_index.html). There unfortunately is no way to get this code running on any system before 10.6.

I'm afraid you'll probably be stuck at an older version of HexFiend via wiki:howto/InstallingOlderPort.

Thank you for your help and the information, it is much appreciated!
I can confirm that version 2.0 of port hexfind is working fine on 10.5 (Leopard), so i'll keep using that version.
