configure library omission, xemacs-21.4.8, Mandrake Linux 8.1

Xemacs version 21.4.8 Platform: i568, Mandrake Linux 8.1 Linux version 2.4.8-26mdk (quintela(a)bi.mandrakesoft.com) (gcc version 2.96 20000731 (Mandrake Linux 8.1 2.96-0.62mdk)) XFree86 Version 4.1.0 / X Window System (protocol Version 11, revision 0, vendor release 6510) Release Date: 2 June 2001 The 'configure' script omits a critical library during the check for 'dlopen' when invoked with configure '--with-dialogs=motif' The library Xp is omitted from the link; the compile/link that fails is: configure:14271: checking for dlopen in -ldl configure:14282: gcc -o conftest -g -O3 -Wall -Wno-switch -Winline \ -Wmissing- prototypes -Wsign-compare -Wshadow \ -I/usr/X11R6/include -L/usr/X11R6/lib conftest.c \ -lXm -ltiff -lpng -ljpeg -lz -lXpm -lXmu -lXt -lXext -lX11 \ -lSM -lICE -ldl -ltermcap -lcurses -lm -lgcc -lc-lgcc \ /usr/lib/crtn.o 1>&5 /usr/X11R6/lib/libXm.so: undefined reference to `XpGetDocumentData' /usr/X11R6/lib/libXm.so: undefined reference to `XpStartPage' /usr/X11R6/lib/libXm.so: undefined reference to `XpQueryExtension' /usr/X11R6/lib/libXm.so: undefined reference to `XpEndPage' /usr/X11R6/lib/libXm.so: undefined reference to `XpEndJob' /usr/X11R6/lib/libXm.so: undefined reference to `XpSelectInput' /usr/X11R6/lib/libXm.so: undefined reference to `XpGetContext' This link will succeed with the addition of '-lXp'. Probably, this would happen with any XFree86 4.1.0 release.
