Building SDL & Qt Versions doesnt work since today [Ubuntu 13.04 64bit]

[Iljalicious]

Hey guys, it's me again.

I update normally both versions of PPSSPP, but since today it's not working
anymore without problems.

I have one command-line for building the SDL-version :

git clone git://github.com/hrydgard/ppsspp.git && cd ppsspp ; git submodule update -i ; ./b.sh && cd build ; ./PPSSPPSDL

But now I got this errors :

/usr/bin/ld: lib/libCore.a(atrac3plus.cpp.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
/usr/bin/ld: note: 'dlclose@@GLIBC_2.2.5' is defined in DSO /lib/x86_64-linux-gnu/libdl.so.2 so try adding it to the linker command line

Do someone, who uses Ubuntu know what's to do? O:
