GPUTILS is described as 'Gputils is a collection of development tools for Microchip (TM) PIC (TM) microcontrollers. It's intended to be compatible with the manufacturer's tools, MPASM, MPLINK and MPLIB' and is a Compiler in the development category. There are four alternatives to GPUTILS for Linux, Mac, Windows and Eclipse. The best GPUTILS alternative is MPLAB X IDE. It's not free, so if you're looking for a free alternative, you could try SDCC - Small Device C Compiler or CPIK.
The MPLAB X IDE is the new graphical, integrated debugging tool set for all of Microchip’s more than 800 8-bit, 16-bit and 32-bit MCUs and digital signal controllers, and memory devices. It includes a feature-rich editor, source-level debugger, project manager, software...

The PicCBuilder is an Eclipse plugin for allowing the use of Eclipse CDT as the editor and builder of projects for Microchip PIC microcontrollers. It creates makefiles that involke the C30 or C32 toolchain to generate the binary files.
