This port might have been requested by some other port (I cannot tell) because I do not need it.

Main.log from PPC Leopard

[ballapete (Peter "Pete" Dyballa)]

I presume Leopard has no memalign() function… (see /opt/mports/trunk/dports/math/fftw-3/files/leopard-no-memalign.patch?)

[kencu (Ken)]

posix_memalign was one of the first things I added to legacysupport, so you might have happiness adding that.

[ballapete (Peter "Pete" Dyballa)]

Replying to kencu:

Yes, with some support it built! It could also run

make test

for which I had to patch line #29 of libraries/liblmdb/Makefile: On Macs SOEXT is usually .dylib… (the test succeeded all)

[ballapete (Peter "Pete" Dyballa)]

Same failure and same cure on PPC Tiger, Mac OS X 10.4.11.

[Wowfunhappy (Jonathan)]

Quick note that I'm also running into this issue on Intel Tiger (10.4.11). I'm ultimately trying to install Git atm. :)

[Wowfunhappy (Jonathan)]

...and, yep, merely adding:

PortGroup           legacysupport 1.0

at the top of the Portfile fixed it!

[kencu (Ken)]

You should find git works well on Tiger -- I had a few issues with it three or four months ago, but I believe those have all been resolved now.

If you get stuck, I do have a fairly full set of archives for Tiger Intel/PPC I can make available to you.
