>Description:
The latest commit to mk/check/check-shlibs.mk removed the leading / from 
line 32.  This results in checking library paths against absolute pathnames in 
DESTDIR, e.g.:

pkg_info: can't find package `lua-5.1.1nb1'
=> Checking for missing run-time search paths in lua-5.1.1nb1
ERROR: /usr/pkgsrc/lang/lua/work.dexamyl/.destdir/usr/pkg/bin/lua:      -llua.5
=> not found
ERROR: *** The programs/libs shown above will not find the listed
ERROR:     shared libraries at runtime.
ERROR:     Please fix the package (add -Wl,-R.../lib in the right places)!
*** Error code 1

Upon discussion of this issue with Klaus Heinz, it seems that this 
change--which is a fix--uncovered a bigger problem:  it is possible that prior 
to this change, no libraries were checked when using relative pathnames.
>How-To-Repeat:
Using DESTDIR support, Try to create a package which installs a shared library.
>Fix:
Find a platform-independent way of doing something like extracting DT_RPATH 
from ELF binaries to construct LD_LIBRARY_PATH, then use this in 
mk/check/check-shlibs.mk.

This problem does not apply unless one is using DESTDIR support.
