Installing binary rpm on Redhat 7.1 - libreadline issue

Hi All! Has anyone else had this problem? I've got readline & readline-devel installed. Given, I'm trying to install an RPM build on a 7.2 sytem onto a 7.1, but... Is it something to do with my (nonexistant) LIBRARY_PATH environment? [erik@proto rpms]$ rpm -Uvh ghc-5.02.2-rh72-1.i386.rpm error: failed dependencies: libreadline.so.4 is needed by ghc-5.02.2-1 [erik@proto rpms]$ rpm -qa | grep readline readline-devel-4.1-9 readline-4.1-9 [erik@proto rpms]$ rpm -ql readline /usr/lib/libhistory.so.4 /usr/lib/libhistory.so.4.1 /usr/lib/libreadline.so.4 /usr/lib/libreadline.so.4.1 Thanks for any insight!
