problem installing octave

[Steven Allen]

Hi All,
I posted this to the forum, but the mailing list may be more appropriate.
I am trying to install octave and get the following error meassage,
lin -v octave
Checking dependencies for octave
Building octave
+ make="/usr/bin/make", MAKES=""
+ CC_EXT="", CXX_EXT=""
+ Enabling gcc wrapper scripts to force optimizations
+ BUILD="i686-pc-linux-gnu"
+ GCCVER="3"
+ CFLAGS="-O2 -mcpu=pentium3 -march=pentium3"
+ CXXFLAGS="-O2 -mcpu=pentium3 -march=pentium3"
+ LDFLAGS=" -s"
+ building "octave" version "2.1.49" in /usr/src
/sbin/lin: line 3: ./configure: No such file or directory
Creating /var/log/lunar/compile/octave-2.1.49.bz2
! Problem detected during BUILD

It appears to me that the source file is not being unpacked. A little
digging in the lunar scripts shows (I think) that this is normally done
in default_pre_build. The existance of a PRE_BUILD script appears to
stop default_pre_build from being called so I assume either it or code
performing the same function should be called from within the PRE_BUILD
script.
Having said the above my bash scripting skills are minimal and I am not
a programmer by trade, so the above may be totally incorrect.
Of course all of the above may also have been caused by something I did.

Hope somebody can help.
