relocation error: ABI change?

[Ludovico Cavedon <ludovico.cavedon@gmail.com>]

Hi,
If you see en error message like this one (from [1]):

qutecom: relocation error: /usr/lib/qutecom/libphapi.so: symbol
CRYPTO_malloc_debug_init, version OPENSSL_0.9.8 not defined in file
libcrypto.so.0.9.8 with link time reference

does it mean than openssl changed ABI without an SO chanage? Or the
NEEDED entries in libphapi are incorrect?

I know that recompilation fixes it, but I do think it is supposed to
happen, so I trying to understand what the cause is.

Thanks,
Ludovico
