library symlink question

[Frank]

I'm creating a few new ports.  The main port has library dependencies on
two of the other ports.  These two ports install like:

/usr/local/lib/libfoo.la
/usr/local/lib/libfoo.so

but they don't create a libfoo.so.1 and make a symlink.  Therefore,
ldconfig doesn't pick them up and if I use LIB_DEPENDS to find them, it
fails.

What is the proper procedure to get around this?

Thanks,
Frank
