Sorry guys... I executed ./configure --prefix=$HOME --with-python PYTHON=/usr/local/bin/python3 make make install and it completed fine (see also below output from 'grep -i 'PYTHON' config.log'). Still after restarting postgres I get: createlang plpython3u sblab ERROR: could not open extension control file "/data/sblab-home/berald01/share/postgresql/extension/plpython3u.control": No such file or directory STATEMENT: CREATE EXTENSION "plpython3u"; ## From config.log grep -i 'PYTHON' config.log $ ./configure --prefix=/Users/berald01 --with-python PYTHON=/usr/local/bin/python3 PATH: /opt/rh/python27/root/usr/bin configure:5399: checking whether to build Python modules configure:7499: checking for python configure:7529: result: /usr/local/bin/python3 configure:7544: checking for Python distutils module configure:7557: checking Python configuration directory configure:7562: result: /usr/local/lib/python3.4/config-3.4m configure:7565: checking Python include directories configure:7575: result: -I/usr/local/include/python3.4m configure:7580: checking how to link an embedded Python application configure:7607: result: -L/usr/local/lib/python3.4/config-3.4m -lpython3.4m -lpthread -ldl -lutil -lm configure:7612: checking whether Python is compiled with thread support configure:29636: checking Python.h usability configure:29653: gcc -c -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -I/usr/local/include/python3.4m -D_GNU_SOURCE conftest.c >&5 configure:29678: checking Python.h presence configure:29693: gcc -E -I/usr/local/include/python3.4m -D_GNU_SOURCE conftest.c configure:29747: checking for Python.h ac_cv_header_Python_h=yes ac_cv_path_PYTHON=/usr/local/bin/python3 PYTHON='/usr/local/bin/python3' configure_args=' '\''--prefix=/Users/berald01'\'' '\''--with-python'\'' '\''PYTHON=/usr/local/bin/python3'\''' python_additional_libs='-lpthread -ldl -lutil -lm' python_enable_shared='0' python_includespec='-I/usr/local/include/python3.4m' python_libdir='/usr/local/lib/python3.4/config-3.4m' python_libspec='-L/usr/local/lib/python3.4/config-3.4m -lpython3.4m' python_majorversion='3' python_version='3.4' with_python='yes'
