 haven't installed Xcode and its command line tools properly.


 I had the same problem, and really I had the C compiler (XCode) installed.
 I tried everything I could find to solve the problem but to no
 avail.[[BR]]
 Today I decided to dig deeper in the problem and with a lot of patch work
 I could get the thing installed.



 If you look into the log file, you will see the following lines:


 {{{
 :info:configure Couldn't find your C compiler
 :info:configure Compilation failed in require at Makefile.PL line 5.
 :info:configure BEGIN failed--compilation aborted at Makefile.PL line 5.
 }}}


 So the real error seems to be in line 5 of Makefile.PL, This line
 contains:


 {{{
 use Devel::CheckLib;
 }}}


 However in my Macports perl5.12 installation there is no Devel::CheckLib
 module. And I couldn't find a port to install it. [[BR]]
 So I decided to take that out, and to disable the check_lib call at line
 32.[[BR]]
 This line checks for the presence of the expat library, which isn't really
 necessary in Macports because of the dependency on expat. [[BR]]
 It would be wiser IMHO to add a port for Devel::CheckLib and take this as
 a dependency.



 The following problem was with the compilation of the Expat Perl module.
 The Makefiles have /usr/bin/gcc-42 as the required C compiler, which I
 don't have. [[BR]]
 I have /usr/bin/gcc, which is a link to llvm-gcc-4.2. So I made
 /usr/bin/gcc-4.2 a link to /usr/bin/gcc and that finally solved the
 problem.



 Apparently the install procedure needs some additional patches.
