Yuck.  It is much better to add /usr/local/lib to /etc/ld.so.conf (or
one of the files in /etc/ld.so.conf.d) and run ldconfig.  I am amazed
that some distributions still do not do this by default.  (The OP says
he is using lubuntu, but standard ubuntu is installed on one of my
computers and that does do so.)

The correct way to find a header is by using pkg-config with guile's
pkg-config file (guile-2.0.pc).  If the build system's 'make
installcheck' does not do this then it is technically a bug but 'make
installcheck' is widely unused and/or broken for this amongst other
reasons and is best ignored. Use 'make check' instead, which uses the
internal build tree. And it is not a good idea to start making symlinks.
