Problems installing PHP - configure errors

I'm having a terrible time trying to update PHP on my server. First I tried to update it to 4.0.6, then I tried 4.1.2. Neither worked. I'm new to this so it's probably my ignorance of something that's causing the errors I'm getting. My server is a Cobalt RaQ4i with Red Hat Linux and Apache - it came with PHP 4.0.3 installed, and MySQL 32.23.10 was installed by my web host (it's a dedicated server). When I try to configure PHP, I get the error "configure: error: unable to find required gettext library". Then after I remove "--with-gettext" from the configure command, I get the error "error: cannot find header files under /usr/sbin/mysqld". Then after I remove "--with-mysql", I get this message "Something is likely to be messed up here, because the configure script was not able to detect a simple feature on your platform. This is often caused by incorrect configuration parameters". Here is the debug.log: CONFIGURE: './configure' '--prefix=/usr' '--with-apxs=/usr/sbin/apxs' '--with-gd' '--enable-safe-mode' '--with-config-file-path=/etc/httpd' '--with-exec-dir=/usr/bin' '--with-zlib' '--enable-magic-quotes' '--with-regex=system' '--with-ttf=/usr/lib/libttf.so' '--enable-track-vars' '--enable-xml' '--disable-debug' '--with-db' '--with-interbase=shared' '--with-pgsql=shared' '--with-ldap' '--with-imap' '--with-imap-ssl' CC: gcc CFLAGS: -g -O2 CPPFLAGS: -DLINUX=22 -DMOD_SSL=208104 -DMOD_PERL -DUSE_PERL_SSI -Dbool=ch ar -DHAS_BOOL -DEAPI -DBIG_SECURITY_HOLE -DCOBALT_RAQ_LED CXX: CXXFLAGS: INCLUDES: -I/usr/include/apache -I$(top_builddir)/Zend -I/usr/include/f reetype -I/usr/include/imap -I/usr/interbase/include -I/usr/local/src/php-4. 1.2/ext/mysql/libmysql LDFLAGS: LIBS: -lldap -llber -lcrypt -lgd -lttf -lz -lcrypt -lresolv -lm -ldl - lnsl -lresolv -lcrypt DLIBS: -lcrypto -lssl -lc-client SAPI: apache PHP_RPATHS: uname -a: Linux admin.host.lshd.com 2.2.16C28_III #1 Mon Jul 30 22:07:58 PDT 2001 i586 unknown gcc -o conftest -g -O2 -DLINUX=22 -DMOD_SSL=208104 -DMOD_PERL -DUSE_PERL_SSI -Dboo l=char -DHAS_BOOL -DEAPI -DBIG_SECURITY_HOLE -DCOBALT_RAQ_LED conftest.c -lldap -llber -lcrypt -lgd -lttf -lz -lcrypt -lresolv -lm -ldl -l nsl -lresolv -lcrypt 1>&5 /usr/bin/ld: cannot find -lgd collect2: ld returned 1 exit status I'm very frustrated.
