Didn't expect you to try to build lazarus because it's a bit of work.

Your spot on, it does need bootstrapping and it was a bit of a bitch to 
build. Three things to download, lazarus + fpc binary and source.
1) Created the directory fpc-2.0.0.x86_64
2) cd fpc-2.0.0.x86_64
3) Untarred the binary which fpc-2.0.0.x86_64-linux.tar in that directory
4) Untarred binary.x86_64-linux.tar
5) Untarred base.x86_64-linux.tar.gz (created bin, lib, man, share)
6) Untarred fpc-2.0.0.source.tar.gz (created fpc)
And that was just to unpack the source. ;-)

cd fpc
make -j1 compiler_cycle PP=/sources/fpc-2.0.0.x86_64/lib/fpc/2.0.0/ppcx64
for d in rtl packages fcl; do
        make -j1 -C $d clean 
make -j1 rtl packages_base_all fcl packages_extra_all 
make -j1 utils PP=/sources/fpc-2.0.0.x86_64/fpc/compiler/ppcx64 
make compiler_install rtl_install fcl_install \
    packages_install utils_install man_install \
FPCMAKE="/sources/fpc-2.0.0.x86_64/fpc/utils/fpcm/fpcmake" \
    INSTALL_PREFIX="/usr" INSTALL_MANDIR="/usr/share/man" \
    doc_install INSTALL_DOCDIR="/usr/share/doc/fpc-2.0.0/"

Building lazarus was pretty easy. make all. I guess that the fpc 
compiler is working but possible incorrectly as lazarus compiled okay.

The base system is a gentoo system and they have a multilib build, so 
you could be correct it may only work with a multilib build.

Tried strace and the output was just about as useless.
["/usr/share/lazarus/startlazarus"], [/* 26 vars */]) = -1 ENOENT (No 
such file or directory)
dup(2)                                  = 3
fcntl(3, F_GETFL)                       = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 1), ...}) = 0

lseek(3, 0, SEEK_CUR)                   = -1 ESPIPE (Illegal seek)
write(3, "strace: exec: No such file or di"..., 40) = 40
close(3)                                = 0

The whole purpose of this was to use a program called ttsubgrab which 
reads a mpeg file with embedded teletext (recorded from a TV card) and 
generates a subrip (.srt) subtitle file so mplayer will show the subtitles.
