Portfile question for 10.6.8

Tue Jun 6 15:46:56 UTC 2023

it looks like the legacy support library is not being included in the link.

This is common when only scripts are used, as there are many flags that might not be considered.

If you run the build on 10.6 using some extra verbosity flags like "-d" it will show you all the ENVVARs and LDFLAGS etc that macports sets. You should see the ones your script needs to account for in that list to get the proper legacysupport library on the link line.
