[albrecht]$ ldd `which gpgsm`
        libgcrypt.so.7 => /usr/local/lib/libgcrypt.so.7 (0x0ff8d000)
        libgpg-error.so.0 => /usr/lib/libgpg-error.so.0 (0x0ff69000)
        libksba.so.8 => /usr/local/lib/libksba.so.8 (0x0ff1a000)
        libz.so.1 => /usr/lib/libz.so.1 (0x0feeb000)
        libc.so.6 => /lib/libc.so.6 (0x0fd8b000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x0fd55000)
        /lib/ld.so.1 => /lib/ld.so.1 (0x30000000)

Afaict, this looks pretty normal to me (note that I created libgpg-error  
rpm's as I use them with gpgme, so it lives in the normal place. But, yes,  
it's 0.6!). So I'm not sure if it's really a linker problem.

O.k., see the full dump below.

Thanks, Albrecht.
