[GRASSLIST:5014] error compiling PNGdriver

[John Gillette]

sparc-sun-solaris2.7
grass5.0.0

I compiled gd2.0.7 (using the included ./config) to install libgd.so.2.0.0
in a local directory (/scratch/local/lib).

I reran ./config for grass and recompiled.  PNG driver chokes
on linking. At step:

gcc -L/scratch/grass500/grass-5.0.0/src/libes/LIB.sparc-sun-solaris2.7  -o /scratch/grass500/grass-5.0.0/dist.sparc-sun-solaris2.7/driver/PNG <list of .o files> -ldriver -lgis -lnsl    -lz  -lsocket  -lnsl -L/scratch/local/lib -lgd
ld: warning: file libucb.so.1: required by /usr/local/lib/libpng.so.2, not found

Undefined symbol sin, cos in libdriver.a(Text2.o)  
 (symbol belongs to implicit dependency /usr/lib/libm.so.1)

ld: fatal: Symbol referencing errors. ... 
*** Error code 1

Can someone help me compile this?  libucb,libm?

Also, is it possible to compile the PNGdriver such that the gd lib is 
included in the driver such that I can erase the gd lib and include files
when I am done? (statically linked?)

Note that GD2.0.7 is brand new and changes have been made to improve the 
auto config. see http://www.boutell.com/gd/

Thank you
