------------
i encountered a problem when building php 5.2.6 from source. i think this issue is related to a check that is not being made regarding libtool. here is my configure command:

./configure --build=i686-redhat-linux-gnu --host=i686-redhat-linux-gnu --target=i386-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --cache-file=../config.cache --with-libdir=lib --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --disable-debug --with-pic --disable-rpath --without-pear --with-bz2 --with-curl --with-exec-dir=/usr/bin --with-freetype-dir=/usr --with-png-dir=/usr --enable-gd-native-ttf --without-gdbm --with-gettext --with-gmp --with-iconv --with-jpeg-dir=/usr --with-openssl --with-png --with-pspell --with-expat-dir=/usr --with-pcre-regex=/usr --with-zlib --with-layout=GNU --enable-exif --enable-ftp --enable-magic-quotes --enable-sockets --enable-sysvsem --enable-sysvshm --enable-sysvmsg --enable-track-vars --enable-trans-sid --enable-yp --enable-wddx --with-kerberos --enable-ucd-snmp-hack --with-unixODBC=shared,/usr --enable-memory-limit --enable-shmop --enable-calendar --enable-dbx --enable-dio --with-mime-magic=/usr/share/file/magic.mime --without-sqlite --with-libxml-dir=/usr --with-xml --with-system-tzdata --with-apxs2=/usr/sbin/apxs --with-mysql --without-gd --without-odbc --disable-dom --disable-dba --without-unixODBC --disable-pdo --disable-xmlreader --disable-xmlwriter --enable-mbstring --with-mcrypt --with-mysqli

i basically copied the configure command from a php 5.1.6 installation from yum and added a few arguments that i needed, like the --with-mcrypt one. that's why configure reports at the end that it didn't understand some parameters, but that's not the issue. after installing all the packages for which configure has complained, it finished correctly and i was able to run make. but make always ends up with the following error when using --with-mcrypt :

/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status

after some struggle i managed to do yum install libtool-ltdl-devel and it worked. it may just work with yum install-ltdl probably, but i installed the whole devel package just to be sure. so this looks to me like a problem in the configure script and thought of mentionning it to you if it's of any help.
