Description:
------------
I am running PHP5.2 and it hangs at checking for flex version.  This occurs with any snapshot I use.  Compiling on 5.0.4 works. 

Reproduce code:
---------------
./buildit script with configure command below.  
GNUMAKE=gmake ./configure       --with-oci8=$ORACLE_HOME \
                --with-expat-dir=/opt/oracle/php/depends \
                --with-gd=/opt/oracle/php/depends \
                --with-jpeg-dir=/opt/oracle/php/depends \
                --with-png-dir=/opt/oracle/php/depends \
                --with-zlib-dir=/opt/oracle/php/depends \
                --with-xpm-dir=/opt/oracle/php/depends \
                --with-ttf=/opt/oracle/php/depends \
                --with-freetype-dir=/opt/oracle/php/depends \
                --with-apxs=$ORACLE_HOME/Apache/Apache/bin/apxs \
                --with-libxml-dir=/opt/oracle/php/depends \
                --prefix=/opt/oracle/php/DEFAULT \
                --enable-gd-native-ttf \
                --with-config-file-path=$ORACLE_HOME/Apache/Apache/conf \
                --with-mysql=/usr/local/mysql \
                --enable-libgcc \
                --enable-track-vars


Expected result:
----------------
Not Hang.

Actual result:
--------------
Hangs at checking for flex version.
