Basically, if you are installing libs in /usr/local/lib, the it would
seem like you would want /usr/local/lib in ld.so.conf.  So it's a
system config issue.

It's also probably dependent on what version of MakeMaker you have
installed.

Swish 2.4.3 does this in the make file:

   $config{LIBS}    = backtick( "$binary --libs" );

which is:

   $ swish-config --libs
   -L/usr/local/lib -lswish-e -lz -lm

And on my machine when I run make I see:

LD_RUN_PATH="/usr/local/lib" cc  -shared -L/usr/local/lib API.o  -o blib/arch/auto/SWISH/API/API.so   -L/usr/local/lib -lswish-e -lz -lm

So on my machine it is indeed setting LD_RUN_PATH.  That may not be
happening on older versions of MakeMaker.



The path is stored in the library:

$ objdump -p blib/arch/auto/SWISH/API/API.so | grep RPATH
  RPATH       /usr/local/lib

Again, that may be dependent on the version of MakeMaker.
