After having updated the OS to version 10.1 I cannot recompile PHP. This is the contain of the debug.log file: CONFIGURE: './configure' '--with-pgsql' '--with- apxs=/usr/local/apache/sbin/apxs' '--with-zlib-dir' '--with- gd=/usr/local/gd' '--with-png-dir' '--with-pdflib=/usr/local/lib' '--enable-magic-quotes' '--enable-debug=no' '--disable-pear' '--with-xml'
