      Yep. Latest checkout (@04ac9b8ce9ca) from the Jan2014 branch builds with all default modules without any issues.

Thanks, Jennie!
The problem was actually BSD sed, not BSD grep.
Should be fixed, now ...
Works for me.  Thanks, for both fixes!
@Dimitar: does it work for you too?

configure:6863: checking compiler type & version
configure:6890: result: clang-Apple LLVM version 5.0 (clang-500.2.79)
(based
on LLVM 3.3svn)
hm, strange, this means that the "grep&sed-magic" to extract the version
number does not work in this case;
in configure[.ag] we do
gcc_ver="`$CC -v 2>&1 | grep -w '[[Vv]]ersion [[0-9]]\+\.[[0-9]]\+'
     | sed 's|^.*[[Vv]]ersion \([[0-9]]\+\(\.[[0-9]]\+\)\+\).*$|\1|'`"
     CC_ver="clang-$gcc_ver"
and this appears to work for clang 3.3 on Linux.
Also, it work "by hand" for me:
echo 'Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)' |
grep -w '[Vv]ersion [0-9]\+\.[0-9]\+' | sed 's|^.*[Vv]ersion
\([0-9]\+\(\.[0-9]\+\)\+\).*$|\1|'
5.0
Not for me:
$ echo 'Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)' |
grep -w '[Vv]ersion [0-9]\+\.[0-9]\+' | sed 's|^.*[Vv]ersion
\([0-9]\+\(\.[0-9]\+\)\+\).*$|\1|'
$ echo 'Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)' |
grep -w '[Vv]ersion [0-9]\+\.[0-9]\+'
$ echo 'Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)' |
grep -w '[Vv]ersion'
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
$ grep --version
grep (BSD grep) 2.5.1-FreeBSD
...
But this should not be a problem (for now), since all relevant checks only
rely on whether we reconized it's clang (which we did), rather than knowing
the exact clang version.
...
No mention of "recognized", but I did find the following:
Good, this means that out configure did "recognize" the compiler
(i.e., it does not warn about not recognizing it)
...
configure:18985: checking whether we have pthread support
configure:18992: result: yes:   -pthread
This means that we indeed did recognized clang and thus set only
PTHREAD_LIBS="-pthread", but not PTHREAD_INCS="-pthread".
Setting PTHREAD_LIBS="-pthread" is required for clang 3.3 on Linux.
This also means that setting PTHREAD_LIBS="-pthread" is "still too much"
(at least) for clang 5.0 on Mac OSX Mavericks.
Thus, we need to debug and fix the clang version number extraction (see
above),
and then disable both PTHREAD_INCS="-pthread" & PTHREAD_LIBS="-pthread"
(only) for clang-5.0 .
Maybe someone else has any idea, which the clang version number extraction
(see above) does not work for Dimitar (i.e., on Mac OSX Mavericks)?
For the time being, maybe you can try the attached patch for configure.ag ?
Your patch seems helping.  Compilation at least continues, although it hits
another error:
.../monetdb5/modules/mal/mal_mapi.c:321:5: error: will never be executed
[-Werror,-Wunreachable-code]
                              break;
                              ^~~~~
but this is easy to fix, I think.

What does your configure output say,
in particular look for "compiler type & version" and "recognized"
