Sorry, but I don't care about legacy OS versions and I will not look into this myself. If you could provide a patch, I would of course commit it.

snowleopardfixes fixes this:

platform darwin 10 {
	depends_lib-append          port:snowleopardfixes
	configure.ldflags-append   -lsnowleopardfixes
}

-- or patch the strnlen function in manually where needed, eg readelf.c, most likely

[ballapete (Peter "Pete" Dyballa)]

Before I could try that I need the patch files mentioned in Portfile. But they cannot be found…

[ballapete (Peter "Pete" Dyballa)]

cannot download patch files

[kencu (Ken)]

I'll make a PR with the snowleopard_fixes portgroup, which solves this.
