a) what do we mean by 'link the libraries'

        a1: at compile time make sure that libFoo.a is
                called out specifically

        a2: put a symbolic link from where the libFoo.so
                actually is to one of the places where you would
                expect to find them for dynamic loading???

b) do you want to avoid this by making sure that the
arguments that are set in your current perl build include
other things such as some other lddlflags - for dynamic linking
at run time????

speaking of which on our solaris boxes I just noticed
that we have the weird pattern:

vladimir: 57:] perl -V | egrep lib
    ld='cc', ldflags =' -L/usr/local/lib -L/opt/SUNWspro/SC4.2/lib '
    libpth=/usr/local/lib /opt/SUNWspro/SC4.2/lib /usr/lib /usr/ccs/lib
    libs=-lsocket -lnsl -ldl -lm -lc
    perllibs=-lsocket -lnsl -ldl -lm -lc
    libc=/lib/libc.so, so=so, useshrplib=false, libperl=libperl.a
    cccdlflags='-KPIC', lddlflags='-G -L/usr/local/lib -L/opt/SUNWspro/SC4.
2/lib'
.....

so does this really mean that the only place where I
can load in the libFoo.so's will be in /usr/local/lib???
