[chuck-users] Unable to build ChucK 1.3.3.0 for ALSA on Arch Linux

[Jeff Jacobson]

After running 'make linux-alsa' things run smoothly until:

g++ -I. -Ilo -O3 -D__LINUX_ALSA__ -D__PLATFORM_LINUX__ -O3
-fno-strict-aliasing -D__CK_SNDFILE_NATIVE__  -c ulib_regex.cpp -o
ulib_regex.o

makefile:144: recipe for target 'util_string.o' failed
make: *** [util_string.o] Error 1

My googling found no similar errors.  Versions of dependencies are as
follows:

alsa-lib 1.0.27.2-1
alsa-utils 1.0.27.2-1
libsndfile 1.0.25-3
gcc 4.8.2-5
flex 2.5.37-1
bison 3.0.1-1
make 4.0-1

I'm new to building software from source so I apologize if this is a
beginner's misunderstanding.  Thanks for any help you can give me; I'm
looking forward to trying ChucK.
