because libopenmpi1 has an unversioned dependency on libibverbs. 1.0.4-1 is in etch, which is preferred over lenny in my /etc/apt/sources.list. > | $ ldd /usr/lib/openmpi/lib/openmpi/mca_btl_openib.so > | /usr/lib/openmpi/lib/openmpi/mca_btl_openib.so: /usr/lib/libibverbs.so.1: > | version BVERBS_1.1' not found (required by > | /usr/lib/openmpi/lib/openmpi/mca_btl_openib.so) > | linux-gate.so.1 => (0xffffe000) > | libibverbs.so.1 => /usr/lib/libibverbs.so.1 (0xb7f04000) > | libpthread.so.0 => /lib/i686/cmov/libpthread.so.0 (0xb7eec000) > | libmpi.so.0 => /usr/lib/libmpi.so.0 (0xb7e67000) > | libopen-rte.so.0 => /usr/lib/libopen-rte.so.0 (0xb7e14000) > | libopen-pal.so.0 => /usr/lib/libopen-pal.so.0 (0xb7dbd000) > | libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xb7db9000) > | libnsl.so.1 => /lib/i686/cmov/libnsl.so.1 (0xb7da1000) > | libutil.so.1 => /lib/i686/cmov/libutil.so.1 (0xb7d9d000) > | libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb7d77000) > | libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb7c2a000) > | libsysfs.so.2 => /lib/libsysfs.so.2 (0xb7c20000) > | /lib/ld-linux.so.2 (0x80000000) > > Ok.

But the first ldd call was with libibverbs 1.0.4-1. > | ii libstdc++6 4.3-20080116-1 The GNU Standard C++ Library v3 > > Did you by chance force the older version in? If so, then it is your bug ;-) No, I didn't force anything. As I said, the dependency on libibverbs1 is unversioned, thus the lenny version fulfils the dependency. > What happens if you update to 1.1.1-1 as the package wants you to? Then it works (see the second ldd call). But libopenmpi1 does not "want" me to update libibverbs1 because there is no versioned dependency.
