Would you test removing files/patch-Makefile.pre.in ?
After removing files/patch-Makefile.pre.in and than building
lang/python27 works for math/saga (with option PYTHON) again :-)
Thanks a lot,

It is caused by building libpython without -pthread, I shall try to fix it.
I am wondering why there is not a run error when "python -m threading"

Yesterday math/saga got updated. Now there is a new option for python
bindings to the SAGA GIS api. This worked well with version 2.7.1 of
lang/python27 until yesterday.
I tried to build math/saga after upgrading to Python version 2.7.2 from
today, but it stops in the configure. As far as I understand the math/saga
configure script has a problem with the 'consistency check of all components
of python development environment', see config.log (line 1347).
-----------------------------------------
configure:16297: checking consistency of all components of python
development environment
configure:16323: cc -o conftest -O2 -pipe -I/usr/local/include
-fno-strict-aliasing -I/usr/local/include/python2.7 -L/usr/local/lib
conftest.c -L/usr/local/lib/python2.7/config -lpython2.7
-Wl,--export-dynamic -lutil>&5
/usr/local/lib/libpython2.7.so: undefined reference to `pthread_create'
-----------------------------------------
This does not happen, if Python 2.7.2 was build _without_ option 'THREADS'.
Then SAGA GIS builds fine.
Listing the dynamic object dependencies of the Python library, there is a
vital difference between Python 2.7.1 and 2.7.2.
Python 2.7.1, build _with_ option 'THREADS':
ldd /usr/local/lib/libpython2.7.so
/usr/local/lib/libpython2.7.so:
libutil.so.9 => /lib/libutil.so.9 (0x413ac000)
libm.so.5 => /lib/libm.so.5 (0x415bd000)
libthr.so.3 => /lib/libthr.so.3 (0x417de000)
libc.so.7 => /lib/libc.so.7 (0x4084a000)
Python 2.7.2, build _with_ option 'THREADS':
ldd /usr/local/lib/libpython2.7.so
/usr/local/lib/libpython2.7.so:
libutil.so.9 => /lib/libutil.so.9 (0x413ac000)
libm.so.5 => /lib/libm.so.5 (0x415bd000)
libc.so.7 => /lib/libc.so.7 (0x4084a000)
It seems that Python does not include libthr.so.3 in version 2.7.2. Is this
intentional? Is there any other way to use the threaded version of Python
now?
Any help would be really appreciated.
Thanks in advance,
Rainer Hurling
