unresolved symbols under AIX 5.1

In march 2003 there was a thread (http://list-archive.xemacs.org/xemacs-beta/200303/msg00165.html,...) about a build failure under AIX 51 due to unresolved references. I'm currently experiencing a similar problem doing something unrelated. smsendbuff [264] ER DS (/usr/lib/libX11.a[shr4.o]) 00022c3c .data R_POS [746] <smsendbuff> smfreebuff [262] ER DS (/usr/lib/libX11.a[shr4.o]) 00022c40 .data R_POS [748] <smfreebuff> smrcvbuff [260] ER DS (/usr/lib/libX11.a[shr4.o]) 00022c44 .data R_POS [750] <smrcvbuff> smconnect [256] ER DS (/usr/lib/libX11.a[shr4.o]) 00022c48 .data R_POS [752] <smconnect> smsocket [254] ER DS (/usr/lib/libX11.a[shr4.o]) 00022c4c .data R_POS [754] <smsocket> smgetbuff [258] ER DS (/usr/lib/libX11.a[shr4.o]) 00022c9c .data R_POS [794] <smgetbuff> smwait [266] ER DS (/usr/lib/libX11.a[shr4.o]) 00023190 .data R_POS [1428] <smwait> __crypt_r [676] ER DS (/usr/lib/libc.a[shr.o]) 00043a98 .data R_POS [3464] <__crypt_r> __setkey_r [680] ER DS (/usr/lib/libc.a[shr.o]) 00043a9c .data R_POS [3466] <__setkey_r> __encrypt_r [678] ER DS (/usr/lib/libc.a[shr.o]) 00043aa0 .data R_POS [3468] <__encrypt_r> Unfortunately, the thread mentioned died out.
