Hmm, about the following configure.in patch:
-AC_CHECK_LIB(dl, dlopen,, AC_MSG_ERROR([*** required dlopen() function not found! ***]))
+AC_SEARCH_LIBS(dlopen, dl,, AC_MSG_ERROR([*** required dlopen() function not found! ***]))
This will first test for dlopen() without any extra libs and only if that
fails, then re-runs the test with "-ldl". Then if that, too, fails, error
message is printed and configure fails.

Not that serious. It means ecasound can't use mlockall() function that is
used to lock memory against swapping. Memory locking is used to increase
realtime reliability. The failing configure tests are:
AC_CHECK_FUNCS(mlockall)
AC_CHECK_FUNCS(munlockall)

This is more serious as it means OSS soundcard support was not succesfully
compiled. You should have 'ECA_COMPILE_OSS' defined in config.h after
running configure. The failed test is:
AC_CHECK_HEADER(sys/soundcard.h,oss_support=yes,oss_support=no)
