Compiler says that IOV_MAX is not defined. I'm not really sure what this is, but it compiled fine on Ubuntu 10.04. I guess that const is not used anymore.
In memcached.c code, we can see that IOV_MAX is defined if the OS is FreeBSD or iOS, so I decided to just define it anyway.
Here is my diff of the code that made it compile, in case you need it.
57,59c57
< #if defined(__FreeBSD__) || defined(__APPLE__)
< # define IOV_MAX 1024
< #endif

> #define IOV_MAX 1024
