I just went through the same thing last week. (Short version of long
story: finally replaced speakers destroyed by CB RF interference and
needed to recompile my audio apps for glibc2 . . .)

The current version of esd is not compatible with the latest version of
ALSA. However, it will use ALSA's OSS eumulation mode just fine. The way
I got around the compile errors is to manually edit config.h after
configure was complete to remove ALSA support.

Nasty, but it worked.
