Not sure if that is a bug, but there is no typo in my commit message.
Here is copy of log from building the devel/chrpath:

===>  Building for chrpath-0.16
gmake[1]: Entering directory '/wrkdirs/usr/ports/devel/chrpath/work/chrpath-0.16'
gmake  all-recursive
gmake[2]: Entering directory '/wrkdirs/usr/ports/devel/chrpath/work/chrpath-0.16'

cc -Wl,-R /usr/local/lib -o prog prog.c
/usr/bin/ld: error: line 1: unknown directive: 

I think they have problem in configuration here:
 LDRPATH= -R 
at this line LDRPATH contains leading whitespace.

But returning to an issue, when I test helloworld with clang using the same invocation it passes " -R /usr/local/lib" correctly I think:
umb at ubuntu:~/tests/155cpio$ clang -Wl,-R /usr/local/lib -v main.c -o temp
