Having problems compiling libmemcached 0.39. Error with hash_plus.o

Heya, so this is my first time asking a question here. Look at me! Anyway..
Trying to get libmemcached 0.39 on my Ubuntu 9.04 box, and here the steps I'm following before I get to a problem:

wget http://launchpad.net/libmemcached/1.0/0.39/+download/libmemcached-0.39.tar.gz
tar zxvf libmemcached-0.39.tar.gz
cd libmemcached-0.39/
./configure
make

I run into problems with the make. Here's the end of the output (last 10 lines of it):

  CCLD clients/memstat
  CC tests/atomsmasher.o
  CCLD tests/atomsmasher
  CXX tests/hash_plus.o
./config/depcomp: line 611: exec: g++: not found
make[2]: *** [tests/hash_plus.o] Error 127
make[2]: Leaving directory `/home/onassar/libmemcached-0.39'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/onassar/libmemcached-0.39'
make: *** [all] Error 2

Any help would be appreciated. Hard to find info on this.
Thanks.
