Compile error - Redhat 7.2 / Php 4.1.1 / Apache 1.3.22

Hi! When I try to compile php 4.1.1 with Apache 1.3.22 on my Redhat 7.2 I get this error: make[1]: Entering directory `/var/tmp/php-4.1.1/Zend' /bin/sh ../libtool --silent --mode=link gcc -O3 -march=i686 -mcpu=i686 -funroll-loops -fomit-frame-pointer -prefer- non-pic -static -o libZend.la -lpam -ldl -lmm -lpspell -lpdf -lpng -ljpeg -lz -lmysqlclient - lz -lgd -lz -lcrypt -lresolv -lm -ldl -lnsl -lresolv -lcrypt zend_language_parser.lo zend_language_scanner.lo zend_ini_parser.lo zend_ini_scanner.lo zend_alloc.lo zend_compile.lo zend_constants.lo zend_dynamic_array.lo zend_execute.lo zend_execute_API.lo zend_highlight.lo zend_llist.lo zend_opcode.lo zend_operators.lo zend_ptr_stack.lo zend_stack.lo zend_variables.lo zend.lo zend_API.lo zend_extensions.lo zend_hash.lo zend_list.lo zend_indent.lo zend_builtin_functions.lo zend_sprintf.lo zend_ini.lo grep: /usr/lib/libltdl.la: No such file or directory sed: can't read /usr/lib/libltdl.la: No such file or directory libtool: link: `/usr/lib/libltdl.la' is not a valid libtool archive make[1]: *** [libZend.la] Error 1 make[1]: Leaving directory `/var/tmp/php-4.1.1/Zend' make: *** [all-recursive] Error 1 Any idea why it fails ??
