building gperftools problem

[GoogleCodeExporter]

What steps will reproduce the problem?
I try to build gperftools on a 64 bit system on linux
1. cd ~/tools/gperftools-2.0 && mkdir gcc-build
2. export CPPFLAGS=-I/home/niuq/tools/libunwind-0.99-beta/gcc-build/include
3. gperftools-2.0/gcc-build$ ../configure --prefix=$PWD CC=gcc CXX=g++ && make

What is the expected output? What do you see instead?
libtool: link: g++ -pthread -Wall -Wwrite-strings -Woverloaded-virtual 
-Wno-sign-compare -fno-builtin-malloc -fno-builtin-free -fno-builtin-realloc 
-fno-builtin-calloc -fno-builtin-cfree -fno-builtin-memalign 
-fno-builtin-posix_memalign -fno-builtin-valloc -fno-builtin-pvalloc 
-Wno-unused-result -DNO_FRAME_POINTER -g -O2 -pthread -o 
.libs/debugallocation_test debugallocation_test-debugallocation_test.o  
./.libs/libtcmalloc_debug.so -lpthread -pthread -Wl,-rpath 
-Wl,/home/niuq/tools/gperftools-2.0/gcc-build/lib
./.libs/libtcmalloc_debug.so: undefined reference to `_Ux86_64_getcontext'
./.libs/libtcmalloc_debug.so: undefined reference to `_ULx86_64_get_reg'
./.libs/libtcmalloc_debug.so: undefined reference to `_ULx86_64_step'
./.libs/libtcmalloc_debug.so: undefined reference to `_ULx86_64_init_local'
collect2: ld returned 1 exit status

This is actually I do not pass 
-L/home/niuq/tools/libunwind-0.99-beta/gcc-build/lib -lunwind problems. But how 
do I pass this information in autoconfig? If i give 
LDFLAGS=-L/home/niuq/tools/libunwind-0.99-beta/gcc-build/lib it can not config 
successfull. 

What version of the product are you using? On what operating system?
libunwind-0.99-beta and gperftools-2.0. On linux cluster. 
uname -a

Glad to here you got it working. Can you share how you got things working? Is 
this something that could be patched?

Closing off as this is not an issue with gperftools and the submitter has 
worked out a solution.
