"make install" doesn't work

[dannad]

Hi,
I am attempting to install ispCP on Debian lenny.
I have reached the "make install" instruction but I am getting the following errors:

Quote:cd ./tools && make install
make[1]: Entering directory `/usr/local/src/ispcp/ispcp-omega-1.0.0/tools'
(cd ./daemon; \
make ispcp_daemon
make[2]: Entering directory `/usr/local/src/ispcp/ispcp-omega-1.0.0/tools/daemon'
gcc -ansi -Wall -Wstrict-prototypes -pedantic -c -O3 -o ispcp_daemon.o ispcp_daemon.c
make[2]: gcc: Command not found
make[2]: *** [ispcp_daemon.o] Error 127
make[2]: Leaving directory `/usr/local/src/ispcp/ispcp-omega-1.0.0/tools/daemon'
make[1]: *** [daemon/ispcp_daemon] Error 2
make[1]: Leaving directory `/usr/local/src/ispcp/ispcp-omega-1.0.0/tools'
make: *** [install] Error 2

Does anyone know what could be wrong?
