The following problems prevent usage of the bundled libraries in the Linux humble bundle version.
1) the 64-bit library directory is called LIBS64, but the VVVVV script is looking for LIB64. Solution obvious, rename it.
2) both the LIBS32 and LIBS64 library directories only include the actual libraries (e.g. libSDL-1.2.so.0.11.3) but not the sonamed symlinks by which the dynamic linker looks for them (e.g. libSDL-1.2.0). readelf -d VVVVV_* LIB*/*.so* | grep NEEDED will tell you the symlink names to use.
Unfortunately I can't then use the bundled libraries -- at least not all of them -- because libmikmod bumped soname to libmikmod.so.3 an enormously long time ago (pre-2005) when libmikmod 3.2 was released, but your code depends on libmikmod.so.2 (probably because Debian is still on libmikmod 3.1.x).
I sometimes get a coredump when using teleporters. This backtrace is using my system copy of libSDL, since yours is stripped. It's not terribly useful since VVVVVV_64 is also stripped, but for what it's worth:

A fix is coming VERY VERY soon, like, within the hour! Sorry about this.
The libraries are better, but still depend on libjpeg.so.6.2. libjpeg's soname is markedly unstable, and has jumped through 7 to 8 in recent years. Distros are using all three :( :( :( so probably shipping a copy of that too would be worthwhile. Easily fixed for me by just moving your copy of libSDL_image-1.2.so out of the way and letting VVVVVV pick up my system copy.
(The coredump looks like it's fixed, but it's quite intermittent, so it's hard to be sure.)
Yeah. Its always hit and miss as to what assumptions we can make of the user base when it comes to Linux. We will certainly tweak and update the Librarys we included.
Also in the near future we will most likely create a .deb package that will allow the user greater control of what library's are installed.
