trying to compile php with pfpro

trying to compile php with pfpro.  This is my configure line:
 
./configure --with-mysql=/usr/local/mysql --with-apxs2=/usr/sbin/apxs --with-gd --with-jpeg-dir=/usr/lib --with-zlib-dir=/usr/lib --enable-gd-native-ttf --with-png --with-ttf --with-freetype-dir=/usr/lib --with-curl=/usr/local --with-config-file-path=/usr/local/lib --with-mcrypt=/usr/lib --with-mhash=/usr/local/lib --with-openssl --with-pfpro=/usr/local/paypal/payflowpro/linuxrh9/lib

 
this configures fine, make is fine, but on make install I get this:
