error when installing ncarg 6

[serra@…]

I am trying to install ncarg 6 +gcc45 on a PowerPC Mac running 10.5. I used the port selfupdate command before installing. I also downloaded the ncarg tar file from the earth system grid and placed it in the appropriate directory in /opt/local. I am able to install all dependencies, but when I get to the patch (g2clib-1.2.1-patches/makefile) I get the error

:debug:patch setting attributes on /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_science_ncarg/ncarg/work/g2clib-1.2.1-patches/makefile :debug:patch euid/egid changed to: 62638/501 :error:patch Target org.macports.patch returned: can't read "build_arc": no such variable :debug:patch Backtrace: can't read "build_arc": no such variable

while executing

"$post $targetname" :info:patch Warning: the following items did not execute (for ncarg): org.macports.activate org.macports.patch org.macports.configure org.macports.build org.macports.destroot org.macports.install :notice:patch Log for ncarg is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_science_ncarg/ncarg/main.log

I've attached the log to this ticket. I searched the tickets but did not see this problem elsewhere. Not sure if I have an environment variable missing? I tried editing the macports.conf build_arch variable to ppc (it was commented out by default) but this did not seem to help.

Thanks, Yolande Serra
