Bug#918988: [debian-mysql] Bug#918988: Maybe I can help with this issue

[Otto Kekäläinen]

Hello!

Thanks for confirming this. So it seems that you had a leftover
php5-mysql package, that was built against an old libmysqlclient
library and that did not work anymore on a new system where most of
all the other software, including probably the whole libc et al C
libraries, were of a newer version.
