it doesn't fix what i think you want to fix. i am getting

$ chrpath /usr/local/bin/gnucap
/usr/local/bin/gnucap: RUNPATH=/usr/local/lib/gnucap:/usr/local/lib

perhaps as intended. note "RUNPATH" here. i thought you need
"--enable-new-dtags" to get this right...

anyway: (if i do not set an LD_LIBRARY_PATH manually) i see
$ /usr/local/bin/gnucap
[..]
load gnucap-default-plugins.so
     ^ ? gnucap-default-plugins.so: cannot open shared object file: No such 
file or directory

please have a look at the plugpath+ branch. it produces

$ chrpath /usr/local/bin/gnucap
/usr/local/bin/gnucap: RUNPATH=/usr/local/lib
$ chrpath /usr/local/lib/libgnucap.so
/usr/local/lib/libgnucap.so: RUNPATH=/usr/local/lib/gnucap

and works for me. i'd be surprised if that didn't work for you. note
that the approach is similar to what the autotools branch does, except
for the new-dtags and the conditional runpath for gnucap.
