Compilation Error w/ 90, 91 and 44, not 42

[Danny Schaffer]

Hi, Im running Mac OS X 10.2.8 on a 500mhz G4.  I am trying to compile 
gaim as per instructions at 
http://alphamonkey.org/view.php?type=notes&id=309.  When i get to the 
"make" step, with libgcrypt-1.1.91, i get this error:

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I/sw/include -g -O2 -Wall -MT 
ath-pthread-compat.lo -MD -MP -MF .deps/ath-pthread-compat.Tpo -c 
ath-pthread-compat.c  -fno-common -DPIC -o .libs/ath-pthread-compat.lo

I get the same error when trying to compile version 1.1.90 and 1.1.44 
as well.  However it works with 1.1.42.  Is there a new dependency im 
missing, other than libgpg-error?  Any help would be much obliged.  
Thank you,
Dan
