Hi,
  As it turns out, this is entirely trivial to fix. Sun has finally added
all of the single-precision versions of cos(), sin(), acos(), etc to their
standard library, so there's no longer a need to use macros to redefine
them to call the double-precision versions. The workaround is a one-line
change to the Makefile created by the configure script. Here's the change
I made in order to get a successful build and link on a Solaris 10/Sparc
machine:

# old, original setting
#CPPFLAGS = -mt -fast -xO3 -native -xarch=v9a -D"sqrtf=sqrt" -D"cosf=cos" -D"sinf=sin" -D"fabsf=fabs" -D"acosf=acos" -DARCH_SOLARIS2_64 $(DEFINES) $(
INCDIRS)

# new, eliminated the macros for single-precision transcendental functions
CPPFLAGS = -mt -fast -xO3 -native -xarch=v9a -DARCH_SOLARIS2_64 $(DEFINES) $(INCDIRS)

Let us know if you need more help compiling on Solaris 10 x86.
We don't have one of those running presently, so you might still find
a bug or two in the VMD source, but it ought to be really close to working.
