OK, the statically compiled version is at:
ftp://gil.di.uminho.pt/pub/users/strange/ldminfo
sha1sum: 71c1451f9cbd1a4256bb072d4c930418acc8e2fb

Anyway, how to compile with the sources of:
- linux-2.4.20
- linux-ldm-0.0.8

ldm=3Dlinux-ldm-0.0.8
kernel=3Dlinux-2.4.20

1. Decompress linux-ldm-0.0.8:
   curl -s http://dl.sourceforge.net/sourceforge/linux-ntfs/$ldm.tar.bz2 \
     | tar xjf -

2. Enter the directory:
   cd $ldm

3. Decompress the Linux kernel sources:
   curl -s ftp://ftp.di.uminho.pt/pub/kernel/v2.4/$kernel.tar.bz2 \
     | tar xjf -

4. Change test/Makefile to compile ldminfo statically:
   sed -e 's/ -o/ -static &/' -i test/Makefile

5. Correct KERNEL path in Makefile:
   sed -e "s,KERNEL.*=3D.*,KERNEL =3D $PWD/$kernel," -i Makefile

6. Force i386 arch in Makefile:
   sed -e 's/-march=3D.*/-march=3Di386/' -i Makefile

7. Generate kernel's option files:
   yes n | make -C $kernel ARCH=3Di386 oldconfig dep

8. Compile ldminfo and ldmutil:
   make ARCH=3Di386

This worked on a Centos 3.8, 32bits but running x86_64 kernel, but not
on my Fedora 8. YMMV.

Shell script:

ldm=3Dlinux-ldm-0.0.8
kernel=3Dlinux-2.4.20
curl -s http://dl.sourceforge.net/sourceforge/linux-ntfs/$ldm.tar.bz2 \
     | tar xjf - &&
cd $ldm &&
curl -s ftp://ftp.di.uminho.pt/pub/kernel/v2.4/$kernel.tar.bz2 \
     | tar xjf - &&
sed -e 's/ -o/ -static &/' -i test/Makefile &&
sed -e "s,KERNEL.*=3D.*,KERNEL =3D $PWD/$kernel," -i Makefile &&
sed -e 's/-march=3D.*/-march=3Di386/' -i Makefile &&
yes n | make -C $kernel ARCH=3Di386 oldconfig dep &&
make ARCH=3Di386
