Hello,

I had to compile VMD myself : I need cave support on Linux and I couldn't find a pre-compiled
binary.

Here is the part of the strace output of vmd_LINUX (the binary) where things start to go wrong :

-- brk(0x8279000) = 0x8279000
open(".vmdrc", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/home/icps/david/.vmdrc", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/O2/Visualiation/Vmd/lib/vmd/.vmdrc", O_RDONLY) = -1 ENOENT (No such file or directory)
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)

The strace -F output of the vmd script goes like this :

rt_sigprocmask(SIG_SETMASK, [INT], [INT], 8) = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [INT], 8) = 0
fork() = 5855
gettimeofday({1087542582, 35618}, NULL) = 0
rt_sigprocmask(SIG_SETMASK, [INT], [INT CHLD], 8) = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [INT], 8) = 0
rt_sigprocmask(SIG_SETMASK, [INT], [INT CHLD], 8) = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [INT], 8) = 0
rt_sigsuspend([INT 34]/home/icps/david/tardists/vmd-1.8.1/LINUX/vmd_LINUX: /home/icps/david/tardists/Mesa-6.0.1/lib/libGL.so.1: no version information
available (required by /home/icps/david/tardists/vmd-1.8.1/LINUX/vmd_LINUX)

and stays stuck here...

I cand send you the entire traces if you fell they would be of any help,
