[R-SIG-Mac] dyld: Symbol not found: _R_tzname

[Qiong Cai]

The address values for tzname from my compilation are shown below.  The
library libR.dylib does not contain any value for tzname.

If possible, could you please pass the complete command line to build your
libR.dylib to me?  I am afraid that something is wrong with the linking
stage.

thanks
Qiong

nm -g lib/libR.dylib | grep tzname

            U _R_tzname

nm -g src/extra/tzone/libtz.a | grep tzname

0000000000003760 D _R_tzname

                 U _R_tzname

nm -g src/extra/tzone/localtime.o | grep tzname

0000000000003760 D _R_tzname
