Creating languages with relative path to shared libraries

When I do a

    createlang -L $MYDIR plpgsql template1

It appears that MYDIR must be an absolute path to a directory containing
plpgsql.so. I am wondering if there is any way to make it work with a
relative path (like ../lib). I am trying to build a database on a
development machine and then copy it on to a production machine. The paths
where it is built are differenct than where it will reside and I am running
into dynamic linking issues. Any ideas?
