use libwrap.so in solaris

On Solaris 10 the libwrap.so library is very commonly used in installing other packages. When installing a program you may encounter the error:

cannot find libwrap.so

This library is commonly installed on Solaris 10. However, it is not in a library path that is exported in bash by default. So one will need to include it into LD_LIBRARY_PATH variable as follows:

export LD_LIBRARY_PATH=/usr/sfw/lib:$LD_LIBRARY_PATH

This will add it to the library path. At this point you can try to compile or install the package again.
