That's fine, however it is a different mechanism to that used on Solaris
(and VMS, and Win32...)  Rather than perpetuating a series of
platform-spefific hacks it would be preferable to have a generic
get_exe_path() function and then to do all the other path fixups in a
portable way.  The library linking issue is external to the perl executable,
and should probably be dealt with in the existing platform-specific hints
