I'm trying to install PostgreSQL and the PostgreSQL libs on RHEL5 using rpms. I'm getting dependency problems: >>>>># rpm --test -ivh postgresql-8.3.1-1PGDG.rhel4.x86_64.rpm postgresql-libs-8.3.1-1PGDG.rhel4.x86_64.rpm warning: postgresql-8.3.1-1PGDG.rhel4.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 442df0f8 error: Failed dependencies: libcrypto.so.4()(64bit) is needed by postgresql-8.3.1-1PGDG.rhel4.x86_64 libreadline.so.4()(64bit) is needed by postgresql-8.3.1-1PGDG.rhel4.x86_64 libssl.so.4()(64bit) is needed by postgresql-8.3.1-1PGDG.rhel4.x86_64 libcrypto.so.4()(64bit) is needed by postgresql-libs-8.3.1-1PGDG.rhel4.x86_64 libssl.so.4()(64bit) is needed by postgresql-libs-8.3.1-1PGDG.rhel4.x86_64 I don't understand the dependency on the so.4 libraries, since on another server the 8.3.1 packages apparently use the so.6 libraries: >>># ldd /usr/bin/postmaster libxslt.so.1 => /usr/lib64/libxslt.so.1 (0x0000003ceb400000) libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x0000003cf0c00000) libpam.so.0 => /lib64/libpam.so.0 (0x0000003cef800000) libssl.so.6 => /lib64/libssl.so.6 (0x0000003cf0000000) libcrypto.so.6 => /lib64/libcrypto.so.6 (0x0000003cedc00000) libgssapi_krb5.so.2 => /usr/lib64/libgssapi_krb5.so.2 (0x0000003ceec00000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x0000003cec400000) libdl.so.2 => /lib64/libdl.so.2 (0x0000003cea000000) libm.so.6 => /lib64/libm.so.6 (0x0000003cea800000) libc.so.6 => /lib64/libc.so.6 (0x0000003ce9c00000) libkrb5.so.3 => /usr/lib64/libkrb5.so.3 (0x0000003cef000000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x0000003ced000000) libz.so.1 => /usr/lib64/libz.so.1 (0x0000003ceb800000) libaudit.so.0 => /lib64/libaudit.so.0 (0x0000003ced400000) libk5crypto.so.3 => /usr/lib64/libk5crypto.so.3 (0x0000003cee400000) libkrb5support.so.0 => /usr/lib64/libkrb5support.so.0 (0x0000003cee800000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x0000003cef400000) libresolv.so.2 => /lib64/libresolv.so.2 (0x0000003cecc00000) /lib64/ld-linux-x86-64.so.2 (0x0000003ce9800000) libselinux.so.1 => /lib64/libselinux.so.1 (0x0000003ceac00000) libsepol.so.1 => /lib64/libsepol.so.1 (0x0000003ceb000000) The so.4 libraries don't exist on either system! Any help would be appreciated. Cheers, Cliff
