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

You can get the following during a configure/make:

/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [sapi/cgi/php-cgi] Error 1

Or:

ar: ltdl/.libs/ltdl.o: No such file or directory
make: *** [ltdl/libltdl.la] Error 1

Or

/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

Which on a red-hated based system is easily resolved with:

# yum install libtool-ltdl-devel

A simply thing, but somehow I forget this every time … The configure-stage will complete without a problem, it will often only occur when running make to build the binaries.
