RedHat and RPM installation trouble

Hello! My system (a mountain bike magazine) has been running without problems for 2 years, but after I fiddled a little with IMP (and removed it), PHP stopped working. I suspect the installation of IMP (with an RPM) did "something", but I have no idea what. I have removed PHP by using RPM, and my plan was to re-install PHP (by using RPM), but all I get is this: -------------- $ rpm -ivh php-4.1.2-7.2.6.i386.rpm error: failed dependencies: libcurl.so.1 is needed by php-4.1.2-7.2.6 libdb-3.2.so is needed by php-4.1.2-7.2.6 libltdl.so.3 is needed by php-4.1.2-7.2.6 libpspell.so.4 is needed by php-4.1.2-7.2.6 --------------- I am not sure which PHP version I ran before deinstalling, but I get the same when I try with an older RPM: --------------- rpm -ivh php-4.0.6-7.i386.rpm error: failed dependencies: libcurl.so.1 is needed by php-4.0.6-7 libdb-3.2.so is needed by php-4.0.6-7 libltdl.so.3 is needed by php-4.0.6-7 libpspell.so.4 is needed by php-4.0.6-7 ---------------- I have looked around for packages providing these, but it is getting more and more complicated with dependencies in all directions, and I need HELP! :-} This, for instance didn't help much: ----------------- $ rpm -q --whatprovides libcurl no package provides libcurl ----------------- And since I leave for two weeks of vacation in 7 hours and nobody else knows anything about Linux, it would be extremely helpful if someone knew what to do. System details: - RedHat 7.2 upgraded to kernel 2.2.22-7.0.2smp (I run "up2date -u" every night) - apache-1.3.27-1.7.1 (from RPM) - All of these: openssl095a-0.9.5a-18 openssh-3.1p1-6 openssh-clients-3.1p1-6 openssh-server-3.1p1-6 openssl-0.9.6-13 openssh-3.1p1-5 openssh-3.1p1-6 openssl-0.9.6b-28 openssh-clients-3.1p1-6 openssl096-0.9.6-13 ANY help appreciated - THANKS! -- -- Christian
