Unable to install devel/bazaar using base from release_1_6 branch, OK with MacPorts 1.5.2

[Adam Mercer]

Hi

I've been trying to install the devel/bazaar port using base from the
release_1_6 branch but the port fails on installation.  However If I
use the 1.5.2 release of base then devel/bazaar installs without
issue. In ticket #13042 [1] the ports maintainer has noticed that the
build environment is not being correctly set when using base from the
release_1_6 branch, e.g.:

DEBUG: Executing org.macports.build (bazaar)
DEBUG: Environment:

whereas using 1.5.2:

DEBUG: Executing org.macports.build (bazaar)
DEBUG: Environment: CFLAGS='-g -O2 -Wall -fno-strict-aliasing
-I'/opt/local/include' -L'/opt/local/lib' -lintl -lneon -lgpgme -lpth'

does anyone know why base from release_1_6 branch is not setting the
build environment correctly?

Cheers

Adam
