BLT problems with Linux Mandrake 8.1

[Raul Bagni]

Hello:

I'm facing to a problem on SWARM with BLT under Operating System Linux 
Mandrake 8.1.

I'm trying the Paul Johnson's source distribution 2.1.131.20020206.

During the SWARM setup I had no problems, the configuration step was ok 
with parameters:
        ./configure --prefix=/usr/local --with-defaultdir=/usr
and the two make steps were ok too.

Now, the heatbugs compilation is ok - setting the SWARMHOME to /usr/local 
-  but, running heatbugs (or any other sample) i receive the following 
error message:

    "BLT support file `bltGraph.tcl' not found
    If the directory `/usr/local/share/blt2.4' not the intended location 
for the BLT support files,
    please adjust BLT_LIBRARY to the right place."

This message come from the TkExtra.m source, where the method 
"ensureBltSupportFiles" check the existence of
'bltGraph.tcl'. But I can't find 'bltGraph.tcl' in Mandrake installation of 
BLT, the .tcl scripts I'm able to find are only in /usr/share/demo. So what 
I can do ?

Anybody have had this kind of problem ?



As already mentioned I use the Mandrake 8.1 Linux distribution with:
BLT2.4u (standard for Mandrake)
gcc-3.0 (standard for Mandrake, note that I use this instead of gcc2.96 
setting the symbolic link in /usr/bin)
gdb-5.0 (standard for Mandrake)
hdf5-1.4.2 (installed in /usr/local)
jdk-1.3.1 (installed in /usr)
libffi-1.20 (installed in /usr/local)
libpng-1.0.12 (standard for Mandrake)
make-3.79.1 (standard for Mandrake)
tcl8.3.3 (standard for Mandrake)
tk8.3.3 (standard for Mandrake)
xpm-3.4k (standard for Mandrake)
zlib-1.1.3 (standard for Mandrake)

You can see here the piece of code responsible for the message. What 
happens if I force the search for
/usr/bin/bltsh ?
