When matplot lib builds on 't2', it says:
BUILDING MATPLOTLIB
matplotlib: 0.99.1
python: 2.6.4 (r264:75706, Jun 5 2010, 17:43:53) [GCC
4.4.1]
platform: sunos5
REQUIRED DEPENDENCIES
numpy: 1.3.0
freetype2: 9.8.3
That version of freetype is not the one in Sage.
when matplot libs starts building with gcc, I see:
gcc -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall
-Wstrict-prototypes -fPIC -DPY_ARRAYAUNIQUE_SYMBOL=MPL_ARRAY_API
-I/rootpool2/local/kirkby/sage-4.4.3/local/lib/python2.6/site-packages/numpy/core/include
-I/usr/sfw/include -I/usr/sfw/include/freetype2 -I/usr/local/include -I.
-I/rootpool2/local/kirkby/sage-4.4.3/local/include/
-I/rootpool2/local/kirkby/sage-4.4.3/local/include/python2.6 -c
src/ft2font.cpp -o build/temp.solaris-2.10-sun4v-2.6/src/ft2font.o
Note how the include path has some directories like -I/usr/sfw/include and
-I/usr/local/include before the Sage directory
-I/rootpool2/local/kirkby/sage-4.4.3/local/include/
Therefore old versions of include files are being included.
There's a warnings given later
In file included from /usr/sfw/include/freetype2/freetype/freetype.h:51,
from src/ft2font.h:14,
from src/ft2font.cpp:1:
/usr/sfw/include/freetype2/freetype/config/ftconfig.h:65:1: warning:

The problem is, we do not want Sage including those files, but rather those
in Sage.
I don't know exactly what is happening, but it may be that the configuration
file
/usr/sfw/bin/freetype-config
is found before $SAGE_LOCAL/bin/freetype-config, so the locations of the
include directories from there are used.
This all looks wrong to me.
I vaguely remember having these problems with matplotlib before (I had
broken freetype installed on some server and it failed to build) and
actually fixing the spkg package in Sage for that. So I guess more
work is needed.

Thank you. I noticed on package (Singular) where CPPFLAGS was not set to
$SAGE_LOCAL/include, and doing so ensured the include files in Sage were found.
I've not tried this with Matplotlib, but it might be a way to work around the
problem if there is no configure option to specify the location of freetype.
