I tried to install rpm-3.0.4-0.33.i386.rpm on Linux 2.2.5-15 and I get an
error saying it needs /bin/bash2. /bin/bash2 is supposedly generated by
rpm2html 1.3. I tried to install rpm2html-1.3-1.i386.rpm and it says it
requires librpm.so.0 which is in rpm-3.0.4-0.33.i386.rpm.
Install bash2 from its own package. Rpm requires bash2 (and not bash of /bin/sh)
because there is a patch in the Red Hat bash2 to parse a shell script and
identify which executables will be executed by that script. Rpm will use
this to generate dependencies for %pre/%post scriptlets.
