[Ipopt] DPOTRF missing in Lapack

Not really. I can just tell you where to start searching ;-).
The message comes from IpLapack.cpp in Ipopt/src/LinAlg, in case that
COIN_HAS_LAPACK is not defined.
IpLapack.cpp includes Ipopt/src/Common/IpoptConfig.h, which itself
includes config_ipopt.h, which has the #define COIN_HAS_LAPACK line.
Maybe you can just rebuild IpLapack.lo and see if there are some
compiler warnings. There should also be a -DHAVE_CONFIG_H in the
compiler flags.
