I just tried to build pspsdk in svn trunk using automake-1.10.1 and autoconf-2.62 but I got an error in the ac_doxygen.m4 and some weird unexpected end of file error in configure.
After substituting all the aclocal autoconf and automake calls in bootstrap.sh with the 1.9, 2.59 and 1.9 versions I was able to build it.
