Help with install please - possible bug?

Hi,
 
Please can you help?
 
Under IRIX the command:-

    install -m 755 -u user1 -g group bin/*.bat bin/*.pl /usr/project

will install all .bin and .pl files in /usr/project/bin

Under LINUX the same command will copy all the files into the
/usr/project directory

i.e. sub-directories are not catered for; all files are copied to the
target root.

The line from our Makefile is as follows:-
 
    install -m 755 -o lrs -g lrs \${libfiles1} \${prefix}
 

Is there any way round this? I can not find a way of doing it and it
would seem some very useful functionality (recursion) is missing in
LINUX which is unusual.

Kind regards,
