Most likely, this is because you don't have /usr/include/ltdl.h, which
is needed to compile programs against libltdl.

Modern distributions typically separate libraries into at least two
packages: the main package, and a "development package" which includes
header files, etc, needed during compilation.  For example, on
Debian-derived systems, the main package is called "libltdl7", and the
development package is called "libltdl-dev".

To compile Guile, you will need the development packages for all of the
libraries needed for Guile.

If you cannot persuade the administrator of your system to install the
needed packages, then there are a number of ways to proceed.  The most
straightforward is to compile+install the needed libraries from source
code into your home directory, and then build Guile against those
locally-installed libraries.  There are a few gotchas, but it is doable.
