I have tried this on rpm 5.0.3 but it fail

https://bugzilla.redhat.com/show_bug.cgi?id=205350


e.g.

rpm -e R R-mvtnorm
/var/tmp/rpm-tmp.48546: line 1: /usr/lib/rpm/R-make-search-index.sh: No such
file or directory
error: %postun(R-mvtnorm-0.8-2.el5.i386) scriptlet failed, exit status 127
[root@handrax tmp]# rpm -v --version
rpm (RPM) 5.0.3
rpmlib 0x28100c00,0x7d831800,0x52504d35

What's happen ? It was fixed, iirc, some time ago also in rpm 4.4.2.-x

Thanks
