Pear install apd fails

I have been trying to install apd library from pear and it fails with the following details: running: phpize configure.in:9: warning: underquoted definition of PHP_WITH_PHP_CONFIG run info '(automake)Extending aclocal' or see http://sources.redhat.com/automake/automake.html#Extending%20aclocal configure.in:32: warning: underquoted definition of PHP_EXT_BUILDDIR configure.in:33: warning: underquoted definition of PHP_EXT_DIR configure.in:34: warning: underquoted definition of PHP_EXT_SRCDIR configure.in:35: warning: underquoted definition of PHP_ALWAYS_SHARED acinclude.m4:19: warning: underquoted definition of PHP_PROG_RE2C /usr/share/aclocal/vorbis.m4:9: warning: underquoted definition of XIPH_PATH_VORBIS /usr/share/aclocal/pkg.m4:5: warning: underquoted definition of PKG_CHECK_MODULES /usr/share/aclocal/ogg.m4:8: warning: underquoted definition of XIPH_PATH_OGG /usr/share/aclocal/libmcrypt.m4:17: warning: underquoted definition of AM_PATH_LIBMCRYPT /usr/share/aclocal/glib.m4:8: warning: underquoted definition of AM_PATH_GLIB Configuring for: PHP Api Version: 20020918 Zend Module Api No: 20020429 Zend Extension Api No: 20021010 The full output can be seen here: http://www.techsatcomputers.com/TEST/apd.txt I am using Fedora core 2 with automake 1.8.3 autoconf 2.59 libtool 1.5.6 php-4.3.8 Does anyone know how to rectify this problem? I have googled a bit and have found a bug report filed at zend pear dev list: http://www.zend.com/lists/pear-dev/200407/msg00627.html Would that bug apply to the problem I am having installing apd? Thanks for your help. Jeffery Fernandez
