Yes, that looks about right.

This is because gcc48's <cmath> header does not define a whole bunch of
C99 math functions in the std:: namespace.

E.g., /usr/local/lib/gcc48/include/c++/cmath has:

   922  #if __cplusplus >= 201103L
   923
   924  #ifdef _GLIBCXX_USE_C99_MATH_TR1
...
   983  #undef log2
   984  #undef log2f
   985  #undef log2l
...
  1032  namespace std _GLIBCXX_VISIBILITY(default)
  1033  {
  1034  _GLIBCXX_BEGIN_NAMESPACE_VERSION
...
  1117    using ::log2;
  1118    using ::log2f;
  1119    using ::log2l;
...
  1678  _GLIBCXX_END_NAMESPACE_VERSION
  1679  } // namespace
  1680
  1681  #endif // _GLIBCXX_USE_C99_MATH_TR1
  1682
  1683  #endif // C++11

and /usr/local/lib/gcc48/include/c++/x86_64-portbld-freebsd9.3/bits/c++config.h
has:

/* Define if C99 functions or macros in <math.h> should be imported in
   <tr1/cmath> in namespace std::tr1. */
/* #undef _GLIBCXX_USE_C99_MATH_TR1 */

It looks like this file is generated at build time, so something in
gcc's configure scripts is turning off the "C99_MATH_TR1" support.

Then again, the name of the define is a bit strange, since this is not
about <tr1/cmath>, but the regular <cmath> header.  It is probably worth
reporting a bug for the gcc port.

I tried this quick hack to work around it:

You will also need to add -D_DECLARE_C99_LDBL_MATH to ${CXXFLAGS}, to
enable the declaration of a number of long double functions in math.h,
otherwise gcc's <cmath> fails to compile with:

/usr/local/lib/gcc48/include/c++/cmath:1043:11: error: '::acoshl' has not been declared
   using ::acoshl;
           ^
