dyld: Symbol not found: _R_tzname

Hi,

I am using clang+gfortran to build R-3.1.2 on Yosemite (10.10.1).  Here's
the versions of the compilers:

1) clang: Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM
3.5svn); Target:
x86_64-apple-darwin14.0.0; Thread model: posix

2) gfortran: 4.9.2 Configured with: ../src/configure
--prefix=/Users/qiongcai/shared/gcc-4.9.2/
--enable-languages=c,c++,fortran,go
--with-gmp=/Users/qiongcai/shared/gcc-infra/
--with-mpfr=/Users/qiongcai/shared/gcc-infra/
--with-mpc=/Users/qiongcai/shared/gcc-infra/
--with-isl=/Users/qiongcai/shared/gcc-infra/
--with-cloog=/Users/qiongcai/shared/gcc-infra/ --enable-checking=release
--enable-shared --enable-lto

Here's the output of "configure":

   R is now configured for x86_64-apple-darwin14.0.0

   Source directory:          .

   Installation directory:    /Library/Frameworks

   C compiler:                clang  -m64 -march=native -mtune=native -O3

   Fortran 77 compiler:       /Users/qiongcai/shared/gcc-4.9.2/bin/gfortran
-m64 -march=native -mtune=native -O3

   C++ compiler:              clang++ -stdlib=libc++  -m64 -march=native
-mtune=native -O3

   C++ 11 compiler:           clang++ -stdlib=libc++  -std=c++11 -m64
-march=native -mtune=native -O3

   Fortran 90/95 compiler:    /Users/qiongcai/shared/gcc-4.9.2/bin/gfortran
-m64 -march=native -mtune=native -O3

   Obj-C compiler:     clang -ObjC -m64 -march=native -mtune=native -O3
-fobjc-exceptions

   Interfaces supported:      X11, aqua, tcltk

   External libraries:        readline

   Additional capabilities:   NLS, ICU

   Options enabled:           framework, shared BLAS, R profiling

   Capabilities skipped:      PNG, JPEG, TIFF, cairo

   Options not enabled:       memory profiling

   Recommended packages:      yes

The compilation seems ok, but there is a dynamic load problem as follows:

   dyld: Symbol not found: _R_tzname

   Referenced from: /Users/qiongcai/Codes/r-projects/R-3.1.2/lib/libR.dylib

   Expected in: flat namespace

  in /Users/qiongcai/Codes/r-projects/R-3.1.2/lib/libR.dylib

   /bin/sh: line 1: 30319 Done                    echo
"tools:::.install_package_description('.', '"../../../library/tools"')"

      30320 Trace/BPT trap: 5       | R_DEFAULT_PACKAGES=NULL ../../../bin/R
--vanilla --slave > /dev/null

Has anyone seen such a problem before? Any clue to fix the problem?


Thanks

Qiong
