A little off the original topic, but for what it's worth, below is how to 
avoid LD_LIBRARY_PATH in a solaris build of 3.14 (beta 2), in a fairly 
generic environment.  (Note that GNU recommends using Solaris as and ld 
with gcc/g++.)

First, make configuration file mods as shown below.  Note I am not doing
the vxworks builds for now.

$ cd /usr/local/epics/r3.14.0beta2/base/configure
$ diff CONFIG_SITE.original CONFIG_SITE
60,61c60
< #CROSS_COMPILER_TARGET_ARCHS=
< CROSS_COMPILER_TARGET_ARCHS=vxWorks-68040 vxWorks-ppc604
---
> CROSS_COMPILER_TARGET_ARCHS=
95c94
< SHARED_LIBRARIES=NO
---
> SHARED_LIBRARIES=YES

$ cd /usr/local/epics/r3.14.0beta2/base/configure/os
$ cat CONFIG_SITE.solaris-sparc-gnu.solaris-sparc-gnu
GNU_DIR = /usr/local
LD = /usr/ccs/bin/ld -r
DEPLIB_DIRS += /usr/local/lib /usr/local/epics/r3.14.0beta2/base/lib/solaris-sparc-gnu
SHRLIB_LDFLAGS_YES = -Wl,-G -Wl,-dy
SYS_SHRLIB_LIBS = posix4 pthread

Then, the procedure, simply:

setenv EPICS_HOST_ARCH solaris-sparc-gnu
cd /usr/local/epics/r3.14.0beta2/base
gmake >& make.log

Note that the  SYS_SHRLIB_LIBS  redefinition was, if I recall correctly, to 
remove the  Crun  from its definition in  CONFIG.Common.solaris-sparc .
The libCrun, however, might be needed to allow R3.13 build extentions to
load R3.14 shared libs, per a comment in that file.  Its inclusion, however,
broke my build on Solaris 8.  Perhaps the build has changed since then, as
this was in flux (e.g. changed from beta1).

Hope this helps.
