in thread programatically setting the LD_LIBRARY_PATH

If you're doing this because a Perl module has a dependency on a native library (e.g. XML::LibXML), and you need to load the library from a non-default path (e.g. you have a version of libxml2 not in /lib or /usr/lib) and you want to avoid modifying LD_LIBRARY_PATH in a wrapper script or some kind of pseudo-wrapper like that shown above, there is another alternative. In the .bs file for the module, place a call to dl_load_file passing the absolute name of the native library. I used an environment variable to store my custom library path:
# Need to find libxml2. Cannot set LD_LIBRARY_PATH as it is already # cached by the linker. So we load libxml2 BEFORE loading # XML::LibXML's library. dl_load_file($ENV{FOO_PATH} . '/lib/os/');

    I was hoping I could use this if LD_LIBRARY_PATH was already set and it was finding the wrong version of the library in the path. Alas, it still finds and loads the wrong version after specifying the correct version here in the bootstrap file. If only there was a way to specify here to skip some of the other bootstrapping process.
