[Not really a RH 6.1 issue, but its the version of rpm that
ships in 6.1]

Recent changes to rpm have made a few parts rather dependant
on the glibc libraries.  Specifically misc/err.c is glibc
dependant - it includes features.h which is a glibc-ism and
uses some functions form it as well...

Some of the functions which are glibc specific are
reimplemented in libmisc.a.  However libmisc.a is not linked
into the majority of programs.  The following patch (at end)
to fix this should be OK on all architectures including RH
linux iteself (since then libmisc is created but empty).

Additionally for solaris I faked up a misc/features.h with
the following contents (its a hack, but it works)

--- start features.h---
#define __P(x) x
#define __BEGIN_DECLS
#define __END_DECLS
#define fputs_unlocked(x,y)     fputs(x,y)
#define __set_errno(x)          errno=x
static char * __progname = "rpm";
--- end features.h---
